实用新型内容Utility model content

本实用新型所采用的技术方案为：The technical scheme adopted by the utility model is:
一种具有测压功能的内窥镜，包括内窥镜手持端，内窥镜手持端上连接有导管，导管的另一端设置有测压球囊，测压球囊连接有气管，气管的另一端连接有压力显示机构。An endoscope with a pressure measurement function, comprising a hand-held end of the endoscope, a catheter is connected to the hand-held end of the endoscope, a pressure measuring balloon is provided at the other end of the catheter, and the pressure measuring balloon is connected to the trachea and the other end of the trachea One end is connected with a pressure display mechanism.
优选地，所述压力显示机构包括活塞筒，活塞筒与气管连通，活塞筒内套设有活塞板，活塞板上固定有活塞杆，活塞杆的另一端连接有密封伸缩气筒，密封伸缩气筒的另一端固定于活塞筒内；活塞筒上设置有压力标识线。Preferably, the pressure display mechanism includes a piston cylinder, the piston cylinder is in communication with a gas pipe, a piston plate is sleeved in the piston cylinder, a piston rod is fixed on the piston plate, and the other end of the piston rod is connected with a sealed telescopic gas cylinder. The other end is fixed in the piston cylinder; the piston cylinder is provided with a pressure marking line.
优选地，所述密封伸缩气筒靠近活塞杆的一端的材料的柔性材料。Preferably, the sealed telescopic gas cylinder is made of a flexible material near one end of the piston rod.
优选地，所述压力标识线包括低压标识线、常压标识线、高压标识线。Preferably, the pressure marking line includes a low pressure marking line, a normal pressure marking line, and a high pressure marking line.
优选地，所述压力显示机构与内窥镜手持端固定或分离。Preferably, the pressure display mechanism is fixed or separated from the handheld end of the endoscope.
优选地，所述导管远离内窥镜手持端的一端内分别安装有光源组件、摄像头、器械通道。Preferably, a light source assembly, a camera, and an instrument channel are respectively installed in the end of the catheter away from the hand-held end of the endoscope.
优选地，所述光源组件的数量为两个，两个光源组件分设于摄像头的两侧。Preferably, the number of the light source components is two, and the two light source components are separately arranged on both sides of the camera.
优选地，所述所述导管远离内窥镜手持端的一段内填充有UV胶或环氧树脂胶中的一种。Preferably, a section of the catheter away from the hand-held end of the endoscope is filled with one of UV glue or epoxy glue.
本实用新型的有益效果为：The beneficial effects of the utility model are:
1.本实用新型的导管伸到人体腔体内后，内部压力会挤压测压球囊。测压球囊内的气缸推动压力显示机构内相应零部件移动，则测压球囊受到周围环境的压力能准确显示出来。本实用新型采用简单的测压球囊，即可实现对腔体进行测压的目的，结构简单，操作方便。工作人员方便对测压球囊和压力显示机 构进行检查和维护，避免使用测压芯片时难以对测压芯片进行检查的情况。当本实用新型的内窥镜用于检查喉部时，测压球囊能准确测量喉部压力。在使用内窥镜对子宫进行检查时，需要向子宫内充入生理盐水，未避免充入生理盐水过量，可通过测压球囊测量充入生理盐水后的子宫的压力，方便操作。1. After the catheter of the present invention extends into the body cavity, the internal pressure will squeeze the pressure measuring balloon. When the cylinder in the pressure measuring balloon pushes the corresponding parts in the pressure display mechanism to move, the pressure of the pressure measuring balloon can be accurately displayed by the surrounding environment. The utility model adopts a simple pressure measuring balloon to realize the purpose of measuring the pressure of the cavity, and has simple structure and convenient operation. The staff can conveniently inspect and maintain the pressure measuring balloon and the pressure display mechanism, avoiding the situation that it is difficult to inspect the pressure measuring chip when the pressure measuring chip is used. When the endoscope of the present invention is used to inspect the larynx, the pressure measuring balloon can accurately measure the pressure of the larynx. When using an endoscope to examine the uterus, it is necessary to fill the uterus with normal saline. Excessive filling of normal saline is not avoided. The pressure of the uterus after filling with normal saline can be measured by the pressure measuring balloon, which is convenient for operation.
2.当测压球囊被挤压后，气管内的气体向活塞筒流动，则气体推动活塞板移动。活塞杆在活塞板的带动下移动，则活塞杆挤压密封伸缩气筒。密封伸缩气筒内充有气体，则密封伸缩气筒被挤压变形。当测压球囊受到的压力变小时，密封伸缩气筒能回复一定形变，则活塞板和活塞杆能回复一定距离，从而，活塞板的位置能准确显示测压球囊所在位置的压力。通过观察活塞板相对于压力表示线的位置，可准确判断压力大小，测压准确、可靠。2. When the pressure measuring balloon is squeezed, the gas in the trachea flows to the piston barrel, and the gas pushes the piston plate to move. When the piston rod moves under the drive of the piston plate, the piston rod squeezes and seals the telescopic cylinder. If the sealed telescopic cylinder is filled with gas, the sealed telescopic cylinder is squeezed and deformed. When the pressure of the pressure measuring balloon becomes smaller, the sealed telescopic cylinder can return to a certain deformation, and the piston plate and the piston rod can return to a certain distance, so that the position of the piston plate can accurately display the pressure at the position of the pressure measuring balloon. By observing the position of the piston plate relative to the pressure indicating line, the pressure can be accurately judged, and the pressure measurement is accurate and reliable.
3.密封伸缩气筒靠近活塞杆的一端的材料的柔性材料，则活塞杆移动后，密封伸缩气筒靠近活塞杆的一端能相应移动，保证活塞板能准确显示压力。并且密封伸缩气筒被压缩后，具有恢复变形的趋势，则当测压球囊所受压力变小时密封伸缩气筒能准确恢复一定距离。3. The flexible material of the material at the end of the sealed telescopic cylinder close to the piston rod, after the piston rod moves, the end of the sealed telescopic cylinder close to the piston rod can move accordingly to ensure that the piston plate can accurately display the pressure. Moreover, after being compressed, the sealed telescopic air cylinder has a tendency to recover from deformation. When the pressure of the pressure measuring balloon becomes smaller, the sealed telescopic air cylinder can accurately restore a certain distance.
4.当活塞板的位置低于低压标识线时，则所测压位置的压力过小。当活塞板处于常压标识线与低压标识线之间则表示所测部位压力正常。当活塞板的位置处于常压标识线和高压标识线之间，则标识所测部位压力略高，需引起注意。当活塞板的位置高于高压线，则所测部位压力过高。当所测部位压力过低或过高，均提示医护人员病人具有相应病症的可能，以采取相应措施。4. When the position of the piston plate is lower than the low pressure mark line, the pressure at the measured pressure position is too small. When the piston plate is between the normal pressure marking line and the low pressure marking line, it means that the pressure at the measured part is normal. When the position of the piston plate is between the normal pressure marking line and the high pressure marking line, the pressure at the measured part of the marking is slightly higher, which requires attention. When the position of the piston plate is higher than the high-pressure line, the pressure at the measured part is too high.

如图1～图3所示，本实施例的内窥镜，包括内窥镜手持端1，内窥镜手持端1上连接有导管2，导管2的另一端设置有测压球囊3，测压球囊3连接有气管4，气管4的另一端连接有压力显示机构5。As shown in Figures 1 to 3, the endoscope of this embodiment includes an endoscope hand-held end 1. A catheter 2 is connected to the endoscope hand-held end 1 and a pressure measuring balloon 3 is provided at the other end of the catheter 2. The pressure measuring balloon 3 is connected with a trachea 4, and the other end of the trachea 4 is connected with a pressure display mechanism 5.
本实用新型的导管2伸到人体腔体内后，内部压力会挤压测压球囊3。测压球囊3内的气缸推动压力显示机构5内相应零部件移动，则测压球囊3受到周围环境的压力能准确显示出来。本实用新型采用简单的测压球囊3，即可实现对腔体进行测压的目的，结构简单，操作方便。工作人员方便对测压球囊3和压力显示机构5进行检查和维护，避免使用测压芯片时难以对测压芯片进行检查的情况。当本实用新型的内窥镜用于检查喉部时，测压球囊3能准确测量喉部压力。在使用内窥镜对子宫进行检查时，需要向子宫内充入生理盐水，未避免充入生理盐水过量，可通过测压球囊3测量充入生理盐水后的子宫的压力，方便操作。After the catheter 2 of the present invention extends into the body cavity, the internal pressure will squeeze the pressure measuring balloon 3. When the air cylinder in the pressure measuring balloon 3 pushes the corresponding parts in the pressure display mechanism 5 to move, the pressure of the pressure measuring balloon 3 by the surrounding environment can be accurately displayed. The utility model adopts a simple pressure measuring balloon 3, which can realize the purpose of measuring the pressure of the cavity, and has a simple structure and convenient operation. The staff can conveniently inspect and maintain the pressure measurement balloon 3 and the pressure display mechanism 5, so as to avoid the situation that it is difficult to inspect the pressure measurement chip when the pressure measurement chip is used. When the endoscope of the present invention is used to inspect the larynx, the pressure measuring balloon 3 can accurately measure the pressure of the larynx. When using an endoscope to examine the uterus, it is necessary to fill the uterus with normal saline. Excessive filling of normal saline is not avoided. The pressure of the uterus after filling with normal saline can be measured by the pressure measuring balloon 3, which is convenient for operation.
具体的，如图4所示，所述压力显示机构5包括活塞筒51，活塞筒51与气管4连通，活塞筒51内套设有活塞板52，活塞板52上固定有活塞杆53，活塞杆53的另一端连接有密封伸缩气筒54，密封伸缩气筒54的另一端固定于活塞筒51内；活塞筒51上设置有压力标识线55。Specifically, as shown in Figure 4, the pressure display mechanism 5 includes a piston barrel 51, the piston barrel 51 communicates with the air pipe 4, the piston barrel 51 is sleeved with a piston plate 52, the piston plate 52 is fixed with a piston rod 53, the piston The other end of the rod 53 is connected with a sealed telescopic cylinder 54, and the other end of the sealed telescopic cylinder 54 is fixed in the piston cylinder 51; the piston cylinder 51 is provided with a pressure identification line 55.
当测压球囊3被挤压后，气管4内的气体向活塞筒51流动，则气体推动活塞板52移动。活塞杆53在活塞板52的带动下移动，则活塞杆53挤压密封伸缩气筒54。密封伸缩气筒54内充有气体，则密封伸缩气筒54被挤压变形。当测压球囊3受到的压力变小时，密封伸缩气筒54能回复一定形变，则活塞板52和活塞杆53能回复一定距离，从而，活塞板52的位置能准确显示测压球囊3所在位置的压力。通过观察活塞板52相对于压力表示线的位置，可准确判断压力大小，测压准确、可靠。When the pressure measuring balloon 3 is squeezed, the gas in the trachea 4 flows to the piston barrel 51, and the gas pushes the piston plate 52 to move. The piston rod 53 is driven by the piston plate 52 to move, and the piston rod 53 squeezes and seals the telescopic cylinder 54. If the airtight air cylinder 54 is filled with gas, the airtight air cylinder 54 is squeezed and deformed. When the pressure of the pressure measuring balloon 3 becomes smaller, the sealed telescopic cylinder 54 can return to a certain deformation, and the piston plate 52 and the piston rod 53 can return to a certain distance, so that the position of the piston plate 52 can accurately display the position of the pressure measuring balloon 3 Positional pressure. By observing the position of the piston plate 52 relative to the pressure indicating line, the pressure can be accurately judged, and the pressure measurement is accurate and reliable.
所述密封伸缩气筒54靠近活塞杆53的一端的材料的柔性材料。密封伸缩气筒54靠近活塞杆53的一端的材料的柔性材料，则活塞杆53移动后，密封伸缩气筒54靠近活塞杆53的一端能相应移动，保证活塞板52能准确显示压力。并且密封伸缩气筒54被压缩后，具有恢复变形的趋势，则当测压球囊3所受压力变小时密封伸缩气筒54能准确恢复一定距离。The sealed telescopic cylinder 54 is made of a flexible material near one end of the piston rod 53. The sealed telescopic cylinder 54 is a flexible material that is close to the end of the piston rod 53. After the piston rod 53 moves, the sealed telescopic cylinder 54 can move correspondingly at the end near the piston rod 53 to ensure that the piston plate 52 can accurately display the pressure. Moreover, after being compressed, the sealed telescopic air cylinder 54 has a tendency to recover from deformation. When the pressure of the pressure measuring balloon 3 becomes smaller, the sealed telescopic air cylinder 54 can accurately recover a certain distance.
更进一步，所述压力标识线55包括低压标识线551、常压标识线552、高压标识线553。当活塞板52的位置低于低压标识线551时，则所测压位置的压 力过小。当活塞板52处于常压标识线552与低压标识线551之间则表示所测部位压力正常。当活塞板52的位置处于常压标识线552和高压标识线553之间，则标识所测部位压力略高，需引起注意。当活塞板52的位置高于高压线，则所测部位压力过高。当所测部位压力过低或过高，均提示医护人员病人具有相应病症的可能，以采取相应措施。Furthermore, the pressure marking line 55 includes a low pressure marking line 551, a normal pressure marking line 552, and a high pressure marking line 553. When the position of the piston plate 52 is lower than the low pressure marking line 551, the pressure at the measured pressure position is too small. When the piston plate 52 is between the normal pressure marking line 552 and the low pressure marking line 551, it indicates that the pressure at the measured part is normal. When the position of the piston plate 52 is between the normal pressure marking line 552 and the high pressure marking line 553, the pressure at the measured part of the marking is slightly higher, which requires attention. When the position of the piston plate 52 is higher than the high-pressure line, the pressure at the measured part is too high. When the pressure of the measured part is too low or too high, it will prompt the medical staff that the patient has the possibility of the corresponding disease, so that corresponding measures can be taken.
根据使用需要，所述压力显示机构5与内窥镜手持端1固定或分离。压力显示机构5与内窥镜手持端1固定时可方便拿取，在手握内窥镜手持端1时，即可观察压力情况。压力显示机构5与内窥镜手持端1分离时，方便对内窥镜手持端1进行操作，避免压力显示机构5对内窥镜手持端1上的各操作按钮造成阻挡。According to the needs of use, the pressure display mechanism 5 is fixed or separated from the hand-held end 1 of the endoscope. The pressure display mechanism 5 can be conveniently taken when it is fixed to the hand-held end 1 of the endoscope, and the pressure can be observed when the hand-held end 1 of the endoscope is held by hand. When the pressure display mechanism 5 is separated from the handheld end 1 of the endoscope, it is convenient to operate the handheld end 1 of the endoscope, and prevents the pressure display mechanism 5 from blocking the operation buttons on the handheld end 1 of the endoscope.
更进一步，如图5所示，所述导管2远离内窥镜手持端1的一端内分别安装有光源组件21、摄像头22、器械通道23。光源组件21能对摄像头22提供光源，则摄像头22能将导管2端部位置的人体组织进行拍摄，方便医务人员实时观察，方便及时发现人体组织的异常情况。器械通道23能用于器械的通过，方便工具通过器械通道23获取目标位置的人体组织。设置器械通道23后，本实用新型不仅可以将导管2移动到确定位置并对该位置进行观察，还能方便获取该位置组织，操作方便。Furthermore, as shown in FIG. 5, a light source assembly 21, a camera 22, and an instrument channel 23 are respectively installed in the end of the catheter 2 away from the hand-held end 1 of the endoscope.

After the instrument channel 23 is provided, the present invention can not only move the catheter 2 to a certain position and observe the position, but also facilitate the acquisition of the tissue at the position, and the operation is convenient.
其中，所述光源组件21的数量为两个，两个光源组件21分设于摄像头22的两侧。两个光源组件21分设于摄像头22的两侧，则摄像头22能够获取足够的光线，保证摄像头22拍摄画面的清晰。人体组织反射足够的光线到摄像头22内，则摄像头22拍摄的画面亮度足够，方便医护人员根据摄像头22拍摄画面对病变进行分析。Wherein, the number of the light source assembly 21 is two, and the two light source assemblies 21 are separately arranged on both sides of the camera 22. The two light source components 21 are separately arranged on both sides of the camera 22, so that the camera 22 can obtain enough light to ensure that the camera 22 captures a clear picture. If the human tissue reflects enough light into the camera 22, the brightness of the picture taken by the camera 22 is sufficient, which is convenient for medical staff to analyze the lesion according to the picture taken by the camera 22.
