本發明係提供一種內視鏡裝置，具有套設於管體遠端一側的擋止件，可提高使用的穩定性。本發明之內視鏡裝置可運用於外科手術，例如頭顱內的患部清創，但不限於此。 The invention provides an endoscope device, which has a stopper sleeved on the distal side of a tube body, which can improve the stability of use. The endoscope device of the present invention can be applied to surgery, such as debridement of the affected part in the skull, but is not limited thereto.

圖1為本發明內視鏡裝置10之一實施例示意圖。如圖1所示，內視鏡裝置10包含外層管100、管體組件110、擋止件140以及握把150。外層管100具有近端100a及遠端100b。舉例而言，近端100a係指靠近握把150的位置，遠端100b係指沿外層管100延伸方向位於外層管100相反於握把150的一端。握把150係固定於外層管100之近端100a。管體組件110與外層管100接近遠端100b之一側結合。如圖1所示，部分之管體組件110係套設於外層管100內，管體組件110的其他部分係伸出於遠端100b外。換言之，管體組件110具有伸出於遠端100b外的伸出段112以及位於外層管內的伸入段。擋止件140係滑動地設置於管體組件110上並位於管體組件110伸出於遠端100b外的部分。擋止件140可相對管體組件110朝接近或遠離遠端100b移動。在圖1的實施例，管體組件110係固定於外層管100，亦即管體組件110突出於遠端100b外的一側至遠端100b的長度不變，但不以此為限。 FIG. 1 is a schematic diagram of an embodiment of an endoscope device 10 according to the present invention. As shown in Figure 1 As shown, the endoscope device 10 includes an outer tube 100, a tube body assembly 110, a stopper 140, and a grip 150. The outer tube 100 has a proximal end 100a and a distal end 100b. For example, the proximal end 100a refers to a position near the grip 150, and the distal end 100b refers to an end of the outer tube 100 opposite to the grip 150 along the extension direction of the outer tube 100. The grip 150 is fixed to the proximal end 100 a of the outer tube 100. The tube body assembly 110 is coupled to one side of the outer tube 100 near the distal end 100b. As shown in FIG. 1, a part of the tube body assembly 110 is sleeved inside the outer tube 100, and other parts of the tube body assembly 110 are protruded out of the distal end 100 b. In other words, the tube assembly 110 has a protruding section 112 protruding outside the distal end 100b and a protruding section located in the outer tube. The blocking member 140 is slidably disposed on the tube body assembly 110 and is located at a portion of the tube body assembly 110 protruding outside the distal end 100 b. The stopper 140 can move relative to the tube assembly 110 toward or away from the distal end 100b. In the embodiment of FIG. 1, the tube assembly 110 is fixed to the outer tube 100, that is, the length of the tube assembly 110 protruding from the side outside the distal end 100 b to the distal end 100 b is unchanged, but not limited thereto.

於一實施例，內視鏡裝置可包含攝影單元，以提供觀察到的畫面。例如圖1所示，握把150具有線路連接於外部之顯示幕20。攝影單元取得的畫面可經由線路傳到顯示幕20上供使用者判讀。就設置位置而言，攝影單元設置於管體組件內且遠離遠端。請參考圖2A。圖2A為管體組件110之一實施例的局部放大圖。具體而言，圖2A係放大管體組件110伸出於遠端外的端部。如圖2A所示，管體組件110內套設有沖吸管160，以提供沖洗材料，或是進行抽吸血塊。例如，沖吸管係伸入握把內的腔體並連接握把後方的抽吸接口12，以連接外部的抽取機，可清除血塊、血水。又例如可將沖吸管連接握把後方的沖洗接口14，以接收像是藥水或其他治療物質。 In an embodiment, the endoscope device may include a photographing unit to provide an observed image. For example, as shown in FIG. 1, the grip 150 has a display screen 20 connected to the outside by wires. The picture obtained by the photographing unit can be transmitted to the display screen 20 via a line for the user to read. As far as the setting position is concerned, the photographing unit is arranged in the tube assembly and is far from the far end. Please refer to FIG. 2A. FIG. 2A is a partially enlarged view of an embodiment of the pipe assembly 110. Specifically, FIG. 2A is an end portion of the enlarged tube body assembly 110 protruding beyond the distal end. As shown in FIG. 2A, a flushing tube 160 is sleeved inside the tube assembly 110 to provide flushing material or to suck blood clots. For example, the flushing pipe is extended into the cavity in the grip and connected to the suction port 12 at the rear of the grip to connect an external extraction machine to remove blood clots and blood water. For another example, the flushing tube can be connected to the flushing port 14 behind the grip to receive medicines or other therapeutic substances.

如圖2A所示，管體組件110內位於沖吸管160附近另設置有攝影單元30。藉此，可利用攝影單元30觀察體內的景像，再利用沖吸管 160治療。此外，管體組件110內位於沖吸管160附近另設置有光源40，以提供照明。光源例如為光纖，利用光纖的端部發光。在其他實施例，光源亦可為LED燈。 As shown in FIG. 2A, a photographing unit 30 is further disposed in the tube assembly 110 near the suction pipe 160. Thereby, the scene in the body can be observed by the photographing unit 30, and the suction pipe can be reused 160 treatments. In addition, a light source 40 is provided in the tube assembly 110 near the flushing tube 160 to provide illumination. The light source is, for example, an optical fiber, and light is emitted by the end of the optical fiber. In other embodiments, the light source may be an LED lamp.

於一實施例，管體組件內的沖吸管為塑膠，包覆於沖吸管外的部分為金屬。藉外部包覆的金屬引導沖吸管穿過硬質表面，例如頭骨，再利用沖吸管進行上述檢查與治療。在其他實施例，包覆於沖吸管以外的部分的材質可視治療部位調整，例如採用剛性較沖吸管大的塑料材質，以提供沖吸管一定的保護。 In one embodiment, the flushing tube in the tube body assembly is plastic, and the part coated outside the flushing tube is metal. The externally coated metal guides the flushing tube through a hard surface, such as a skull, and then uses the flushing tube to perform the above inspections and treatments. In other embodiments, the material covering the parts other than the suction pipe can be adjusted according to the treatment site. For example, a plastic material that is more rigid than the suction pipe is used to provide certain protection for the suction pipe.

圖2B為管體組件110之另一實施例的局部放大圖。如圖2B所示，沖吸管160可配置為自管體組件110端部突出一段長度。藉此，位於前方的沖吸管160可先將患部清除，避免體內液體先接觸到攝影單元30，以提供較佳觀察效果。於一實施例，沖吸管160係固設於外部包覆的部分，亦即圖2B中所示沖吸管160突出的距離係為固定長度，但不以此為限。 FIG. 2B is a partially enlarged view of another embodiment of the pipe body assembly 110. As shown in FIG. 2B, the suction pipe 160 may be configured to protrude from the end of the pipe body assembly 110 for a length. Thereby, the flushing tube 160 located in the front can remove the affected part first, and avoid the liquid in the body from contacting the photographing unit 30 first, so as to provide better observation effect. In an embodiment, the suction pipe 160 is fixedly disposed on the outer covering part, that is, the protruding distance of the suction pipe 160 shown in FIG. 2B is a fixed length, but is not limited thereto.

請參考圖1與圖3，其中圖3為擋止件140之一實施例的放大圖。擋止件140沿橫切外層管延伸方向具有徑向長度D，如圖3所示，擋止件接近外層管100之一側(參考圖1)具有窄口部142，徑向長度D隨擋止件140遠離遠端100b方向而漸增，且擋止件140遠離遠端100b之一側形成寬口部144。於一實施例，寬口部144的形狀可為漏斗狀；在不同實施例中，寬口部144與窄口部142可分別為兩個環，兩者之間以幅條連接。舉例而言，寬口部144所在之一側可壓在一接觸面上(例如頭骨表面)，突出於寬口部以外的管體組件係***顱腔中。藉由此一設計，擋止件140自接觸面上得到反作用力以支撐管體組件，以控制管體組件的伸入距離，並提高穩定性。 Please refer to FIG. 1 and FIG. 3, wherein FIG. 3 is an enlarged view of an embodiment of the blocking member 140. The stopper 140 has a radial length D in a direction transverse to the extension of the outer tube. As shown in FIG. 3, the stopper has a narrow mouth portion 142 near one side of the outer tube 100 (refer to FIG. 1), and the radial length D follows the stop. The stopper 140 gradually increases away from the distal end 100b, and a wide mouth portion 144 is formed on one side of the stopper 140 remote from the distal end 100b. In one embodiment, the shape of the wide-mouth portion 144 may be funnel-shaped. In different embodiments, the wide-mouth portion 144 and the narrow-mouth portion 142 may be two rings, and the two are connected by a spoke. For example, one side of the wide mouth portion 144 may be pressed against a contact surface (such as the surface of a skull), and a tube body component protruding beyond the wide mouth portion is inserted into the cranial cavity. With this design, the stopper 140 receives a reaction force from the contact surface to support the pipe body assembly, to control the extension distance of the pipe body assembly, and to improve stability.

管體組件突出於遠端外之端部與擋止件的距離係可調整。請參考圖1與圖4，其中圖4為對應圖1之內視鏡裝置10作動之一實施例示意圖。如圖1所示，內視鏡裝置10包含彈簧190，其係設置於管體組件110上，且位於外層管100遠端100b與擋止件140之間。如圖4所示，當推動握把150朝擋止件140移動(沿箭號方向)，且擋止件140壓在頭骨上(圖未示)，此時擋止件140反向壓縮彈簧190，而管體組件110突出於寬口部以外的長度增加。如此一來，可微調管體組件端部與體內患部的距離。藉此設計，在推動握把時，可利用擋止件作固定，減輕使用者手部晃動的影響，提高操作精確性。 The distance between the end of the tube body component protruding beyond the distal end and the stopper is adjustable. please Referring to FIG. 1 and FIG. 4, FIG. 4 is a schematic diagram of an embodiment corresponding to the operation of the endoscope device 10 of FIG. 1. As shown in FIG. 1, the endoscope device 10 includes a spring 190, which is disposed on the tube assembly 110 and is located between the distal end 100 b of the outer tube 100 and the stopper 140. As shown in FIG. 4, when the grip 150 is pushed toward the stopper 140 (in the direction of the arrow), and the stopper 140 is pressed on the skull (not shown), the stopper 140 compresses the spring 190 in the reverse direction at this time. The length of the tube body assembly 110 protruding beyond the wide mouth portion increases. In this way, the distance between the end of the tube body component and the affected part in the body can be fine-tuned. With this design, when the grip is pushed, the stopper can be used for fixing to reduce the influence of the user's hand shaking and improve the operation accuracy.

圖5A為本發明內視鏡裝置10之另一實施例示意圖。與前述實施例的差異在於，管體組件110包含有中層管120和內層管130。如圖5A所示，中層管120係套設於外層管100內。中層管120外表面具有螺紋，並與外層管100彼此螺接(參考圖5B)；但在不同實施例中，中層管120及外層管100間亦可藉由其他的機構設計來達成相對伸縮或移動的效果。內層管130部分套設於中層管120內。內層管120具有突出於遠端100b外之接觸端132。擋止件140係套設於內層管130外，且擋止件140係相對中層管120於遠端及接觸端之間移動。如圖5A所示，內視鏡裝置10包含彈簧190，其係設置於中層管120與擋止件140之間。 FIG. 5A is a schematic diagram of another embodiment of an endoscope device 10 according to the present invention. The difference from the foregoing embodiment is that the pipe body assembly 110 includes a middle-layer pipe 120 and an inner-layer pipe 130. As shown in FIG. 5A, the middle-layer tube 120 is sleeved inside the outer-layer tube 100. The outer surface of the middle-layer pipe 120 is threaded and is screwed to the outer-layer pipe 100 (refer to FIG. 5B); however, in other embodiments, the middle-layer pipe 120 and the outer-layer pipe 100 may be designed to achieve relative expansion or contraction through other mechanisms Effect of movement. The inner tube 130 is partially sleeved in the middle tube 120. The inner tube 120 has a contact end 132 protruding beyond the distal end 100b. The blocking member 140 is sleeved outside the inner tube 130, and the blocking member 140 moves between the distal end and the contact end relative to the middle tube 120. As shown in FIG. 5A, the endoscope device 10 includes a spring 190, which is disposed between the middle tube 120 and the stopper 140.

另外，如前所述，內視鏡裝置可如圖2A所示於管體組件內設置沖吸管、攝影單元與光源。例如，將沖吸管套設於內層管內，且沖吸管係沿內層管伸入握把內的腔體，以接收沖洗材料或是與外部的抽取機連接。攝影單元及光源可設置於內層管內且接近接觸端，以觀察體內的景像。於一實施例，沖吸管為塑膠，而內層管係為金屬，藉金屬材質的內層管引導沖吸管穿過硬質表面，例如頭骨。 In addition, as described above, the endoscope device can be provided with a flushing tube, a photographing unit, and a light source in the tube assembly as shown in FIG. 2A. For example, the flushing tube is sleeved in the inner tube, and the flushing tube extends into the cavity in the grip along the inner tube to receive the flushing material or connect with the external extraction machine. The photographing unit and the light source can be arranged in the inner tube and close to the contact end to observe the scene in the body. In one embodiment, the suction pipe is plastic and the inner pipe is metal. The inner pipe of metal material is used to guide the pipe through a hard surface, such as a skull.

圖5B及圖5C為內視鏡裝置10作動之一另實施例示意圖。如圖5A及圖5B所示，中層管120可自遠端100b突出且相對外層管100移動於伸出位置及縮回位置。換言之，在圖5A至圖5C的實施例，由中層管120和內層管130所組成的管體組件可相對於外層管100移動。如圖5A所示，中層管120係位於縮回位置。如圖5B所示，當中層管120朝伸出位置移動(沿箭號方向)，彈簧190隨中層管120帶動而將擋止件140朝遠離遠端100b方向推動，此時接觸端132至遠端100b的長度增長。藉此，內層管130的接觸端132至遠端100b的長度可隨中層管120的帶動而調整。 5B and 5C are schematic diagrams of another embodiment of the operation of the endoscope device 10. As shown in FIGS. 5A and 5B, the middle-layer tube 120 can protrude from the distal end 100 b and can be moved to an extended position and a retracted position relative to the outer-layer tube 100. In other words, in the embodiment of FIGS. 5A to 5C, the pipe body assembly composed of the middle-layer pipe 120 and the inner-layer pipe 130 can be moved relative to the outer-layer pipe 100. As shown in FIG. 5A, the middle-layer tube 120 is located in the retracted position. As shown in FIG. 5B, the middle tube 120 moves toward the extended position (in the direction of the arrow). The spring 190 drives the middle tube 120 to push the stopper 140 away from the distal end 100b. At this time, the contact end 132 is far away. The length of the end 100b is increased. Accordingly, the length from the contact end 132 to the distal end 100 b of the inner tube 130 can be adjusted as the middle tube 120 is driven.

如圖5C所示，當推動握把150朝擋止件140移動(沿箭號方向)，且擋止件140壓在頭骨上(圖未示)，此時擋止件140反向壓縮彈簧190，而接觸端132至寬口部的距離增加。如此一來，可微調接觸端與體內患部的距離。藉此設計，在推動握把時，可利用擋止件作固定，減輕使用者手部晃動的影響，提高操作精確性。 As shown in FIG. 5C, when the grip 150 is pushed toward the stopper 140 (in the direction of the arrow), and the stopper 140 is pressed on the skull (not shown), the stopper 140 compresses the spring 190 in the reverse direction at this time. , And the distance from the contact end 132 to the wide mouth portion increases. In this way, the distance between the contact end and the affected part in the body can be fine-tuned. With this design, when the grip is pushed, the stopper can be used for fixing to reduce the influence of the user's hand shaking and improve the operation accuracy.

圖6A及圖6B為內視鏡裝置10具有按鈕控制之一實施例示意圖。如圖6A所示，內層管130較擋止件140更接近接觸端132的位置具有可彎折部134。具體而言，內層管130外表面於可彎折部134的位置係形成複數切縫136，使該處較具可撓性。握把150上設置有按鈕170及搖桿180。按鈕170可控制沖吸管相對內層管130移動。例如，沖吸管伸入握把內的部分係與驅動裝置連接，且按鈕與驅動裝置電連接，按壓按鈕時可啟動驅動裝置將沖吸管伸長。如圖6B所示，按壓按鈕170時，沖吸管160突出於內層管130外。換言之，沖吸管160自接觸端132突出於內層管130管口的長度係可調整。藉此可在內層管伸入體內後調整沖吸管管口與內層管內其它元件(例如攝影單元)的相對距離，以提供使用的方便性。 FIG. 6A and FIG. 6B are schematic diagrams of an embodiment of the endoscope device 10 with a button control. As shown in FIG. 6A, the inner layer tube 130 has a bendable portion 134 closer to the contact end 132 than the stopper 140. Specifically, a plurality of slits 136 are formed on the outer surface of the inner layer tube 130 at the position of the bendable portion 134 to make the portion more flexible. A button 170 and a rocker 180 are provided on the grip 150. The button 170 controls the movement of the suction tube relative to the inner tube 130. For example, the part of the flushing pipe that extends into the grip is connected to the driving device, and the button is electrically connected to the driving device. When the button is pressed, the driving device can be activated to extend the flushing tube. As shown in FIG. 6B, when the button 170 is pressed, the suction pipe 160 protrudes out of the inner layer pipe 130. In other words, the length of the suction tube 160 protruding from the contact end 132 beyond the nozzle of the inner tube 130 is adjustable. In this way, the relative distance between the nozzle of the suction tube and other components (such as a photography unit) in the inner tube can be adjusted after the inner tube is extended into the body, so as to provide convenience.

圖7為內層管130彎曲之一實施例示意圖。配合前述之搖桿可控制內層管的擺動，如圖7所示，內層管130自原位置(虛線繪示處)朝偏離內層管130的軸向A之一側彎曲。藉此，搖桿可控制內層管自可彎折部產生彎曲，例如朝上下左右擺動，以增加攝影單元的視野。藉此設計，例如在接近患部附近時，可利用擋止件控制管體伸入，並配合搖桿擺動管體進行觀察，可避免檢查有所遺漏，提高準確性。 FIG. 7 is a schematic diagram of an embodiment in which the inner tube 130 is bent. The swing of the inner tube can be controlled with the aforementioned rocker. As shown in FIG. 7, the inner tube 130 is biased from the original position (shown by the dotted line). One side of the inner layer pipe 130 from the axial direction A is bent. Thereby, the rocker can control the inner layer tube to bend from the bendable portion, such as swinging up, down, left and right to increase the field of view of the photographing unit. With this design, for example, when approaching the vicinity of the affected part, the stopper can be used to control the extension of the pipe body and cooperate with the rocker to swing the pipe body to observe, which can avoid inspection omissions and improve accuracy.

圖8為本發明內視鏡裝置10之另一實施例示意圖。如圖8所示，擋止件140接近外層管100之一端具有套筒141。彈簧190之一端係抵接套筒141，且彈簧190之另一端係抵接該中層管120。在圖8之實施例，套筒141係擋止件140的一部份，作為窄口部的延伸段並提供使用者接觸擋止件140時，有足夠的握持面積，亦避免使用者直接碰觸到內層管130而影響操作過程。在其它實施例，套筒141可作為獨立的元件並組裝於擋止件140。 FIG. 8 is a schematic diagram of another embodiment of the endoscope device 10 according to the present invention. As shown in FIG. 8, the stopper 140 has a sleeve 141 near one end of the outer tube 100. One end of the spring 190 abuts the sleeve 141, and the other end of the spring 190 abuts the middle-layer tube 120. In the embodiment of FIG. 8, the sleeve 141 is a part of the stopper 140 and serves as an extension of the narrow mouth portion and provides a sufficient holding area for the user to contact the stopper 140, and also avoids the user directly Touching the inner tube 130 affects the operation process. In other embodiments, the sleeve 141 can be used as a separate component and assembled to the stopper 140.

圖9A為套筒141之一實施例的放大圖。如圖9A所示，自遠端一側觀之，套筒141背向接觸端之一側形成第一導槽143。另外如圖9B繪示之中層管120的局部放大圖，中層管120形成第二導槽123(位於中層管朝向接觸端之一側)。第一導槽143與第二導槽123相向設置。彈簧190兩端分別容納於第一導槽143及第二導槽內123。例如，彈簧190之一端係抵接第一導槽143內的表面143a，且彈簧190之另一端係抵接該中層管120內的表面123a。 FIG. 9A is an enlarged view of an embodiment of the sleeve 141. As shown in FIG. 9A, viewed from the distal side, the sleeve 141 forms a first guide groove 143 on one side facing away from the contact end. In addition, as shown in FIG. 9B, a partial enlarged view of the middle-layer tube 120 shows that the middle-layer tube 120 forms a second guide groove 123 (located on one side of the middle-layer tube facing the contact end). The first guide groove 143 is opposite to the second guide groove 123. The two ends of the spring 190 are respectively received in the first guide groove 143 and the second guide groove 123. For example, one end of the spring 190 is in contact with the surface 143 a in the first guide groove 143, and the other end of the spring 190 is in contact with the surface 123 a in the middle-layer tube 120.

圖10為擋止件140之一實施例的立體圖。如圖10所示，擋止件140有幅條146與外緣148。擋止件140的徑向長度隨遠離套筒之一側漸增，在遠離套筒之一側形成外緣。舉例而言，擋止件可藉外緣壓在一接觸面上(例如顱骨表面)，突出於外緣以外的內層管係***頭顱中。藉此設計，可提供使用者額外的視野，例如將管體前端對準傷口表面時，可自幅條間的空隙觀察到管體前方的情形，增加操作方便性。 FIG. 10 is a perspective view of an embodiment of the stopper 140. As shown in FIG. 10, the stopper 140 has a spoke 146 and an outer edge 148. The radial length of the stopper 140 gradually increases with one side away from the sleeve, and an outer edge is formed at one side away from the sleeve. For example, the stopper can be pressed into a contact surface (such as the skull surface) by the outer edge, and an inner tube system protruding beyond the outer edge can be inserted into the skull. This design can provide users with additional vision. For example, when the front end of the tube is aligned with the wound surface, the situation in front of the tube can be observed from the space between the spokes, which increases the convenience of operation.

圖11為對應圖8之內視鏡裝置10作動之一實施例示意圖。如圖11所示，當推動握把150朝擋止件140移動(沿箭號方向)，且擋止件140相反於套筒141之一端(外緣的位置)抵接並壓迫例如顱骨之接觸面上(圖未示)，此時套筒141反向朝中層管120壓縮彈簧190，而接觸端132至擋止件140的距離增加。如此一來，可微調接觸端與體內患部的距離。藉此設計，在推動握把時，可利用擋止件作固定，減輕使用者手部晃動的影響，提高操作精確性。 FIG. 11 is a schematic diagram of an embodiment corresponding to the operation of the endoscope device 10 of FIG. 8. As shown in FIG. 11, when the grip 150 is pushed toward the stopper 140 (in the direction of the arrow), and the stopper 140 is opposite to one end of the sleeve 141 (the position of the outer edge) and abuts against the contact of the skull, for example On the surface (not shown), at this time, the sleeve 141 compresses the spring 190 toward the middle tube 120 in the opposite direction, and the distance from the contact end 132 to the stopper 140 increases. In this way, the distance between the contact end and the affected part in the body can be fine-tuned. With this design, when the grip is pushed, the stopper can be used for fixing to reduce the influence of the user's hand shaking and improve the operation accuracy.
