Description

Single-port laparoscopic surgery access platform

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a single-port laparoscopic surgery access platform.

Background

With the progress of minimally invasive surgery in recent years, single-port laparoscopic surgery has been vigorously developed in the gynecological field due to the advantages of small body surface wound, good cosmetic effect, pain relief and the like, and can be applied to such procedures as ovarian cyst removal, salpingo-oophorectomy, salpingectomy, salpingout ectopic pregnancy, pelvic adhesion, salpingomy, ovarian perforation and even hysteromyoma removal. Only one incision is formed in the single-port laparoscopic surgery, and the incision is small, so that the requirement on an instrument channel of the access platform is higher; and the pneumoperitoneum technology is mostly adopted during the single-port laparoscopic surgery, so the requirement on the air tightness of the access platform is also met.

For example, patent document CN108245205A proposes an access channel of a single-port laparoscope and a manufacturing method thereof, which includes a glove, wherein the end of at least one finger stall on the glove is intersected to form a through hole, an instrument penetration tube is arranged at the through hole, and the instrument penetration tube is used for the sealed penetration of instruments. In the technical document, an instrument penetration tube is arranged in the finger stall in a silk thread binding mode, and the air tightness is poor because the gap between the finger stall and the instrument penetration tube cannot be completely sealed; the instrument penetrating pipe keeps the air tightness with the instrument, and the inner diameter of the instrument penetrating pipe is thin, so that the instrument is inconvenient to pass in and out; and the appliance penetrating pipe is completely communicated when the appliance is not installed, so that a special person is required to seal the appliance penetrating pipe when the appliance is replaced in an operation, otherwise, carbon dioxide in the abdominal cavity can be leaked in time.

Still like patent document CN212234619U provides a multichannel haplopore laparoscopic surgery puncture ware, including connector and flexible sealed cowling, the connector includes solid fixed ring of passageway and the solid fixed ring of platform, the bottom cover of flexible sealed cowling is established on solid fixed ring of platform and is connected with solid fixed ring of platform, set up flutedly on the solid fixed ring's of passageway inside wall, install the silica gel sealing washer in the recess, install built-in ring in the flexible sealed cowling, the top fixed mounting of flexible sealed cowling has a plurality of passageway of going into the way, the top fixed mounting of flexible sealed cowling has the gas injection valve. The platform fixing ring and the flexible sealing cover of the operation puncture outfit are fixedly connected, and the silica gel sealing ring is arranged on the channel fixing ring, so that the air tightness is stronger, but the operation puncture outfit is only provided with the air injection valve, smoke in the abdominal cavity can not be effectively discharged in the operation, and the operation smoke is accumulated in the abdominal cavity, particularly at the focus, so that the operation visual field is influenced, and the operation is influenced.

Disclosure of Invention

The invention aims to solve the technical problem of providing a single-port laparoscopic surgery access platform aiming at the defects of the prior art.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

a single-port laparoscopic surgery access platform comprises an incision protective sleeve, an operation platform and a smoke exhaust assembly;

any two of the incision protective sleeve, the operation platform and the smoke exhaust assembly can be clamped and the clamped part is sealed;

the smoke exhaust assembly comprises a connecting ring, a smoke exhaust channel connected to the outer side of the connecting ring, a plurality of miniature smoke exhaust pipes connected to the inner side of the connecting ring, and an expansion ring fixedly connected with the tail ends of all the smoke exhaust pipes;

the connecting ring is provided with a sealed inner cavity for communicating the smoke exhaust channel with all the smoke exhaust pipes;

the connection points of the smoke exhaust pipes and the connection rings are uniformly distributed along the circumferential direction of the connection rings, the connection points of the smoke exhaust pipes and the expansion rings are uniformly distributed along the circumferential direction of the expansion rings, and the parts of the smoke exhaust pipes between the connection points and the expansion rings are equal in length;

the expansion ring utilizes the self-expansion performance to pull the smoke exhaust pipe to diffuse outwards;

when the smoke exhaust assembly is clamped with the cut protection sleeve, the smoke exhaust pipe penetrates through the cut protection sleeve.

Furthermore, the tail end of the smoke exhaust pipe is fixedly connected with the expansion ring after penetrating through the expansion ring.

Further, the air hole of the smoke exhaust pipe is positioned at one end close to the expansion ring.

Further, the air holes are arranged in rows on one side, far away from the expansion ring, of the smoke exhaust pipe.

Furthermore, the clamping device also comprises a lock catch used for automatically locking the clamping part.

Furthermore, the operating platform comprises a sealing cover, the sealing cover is soft, and a plurality of instrument channels are fixedly arranged at the upper part of the sealing cover; the instrument channels all have self-sealing properties.

Further, the sealing cover is transparent.

Further, a gas injection channel is further arranged on the sealing cover.

In the single-port laparoscopic surgery, when an energy instrument is applied for electrocoagulation and electrosection, a large amount of smoke and water vapor can be generated, and the smoke and the water vapor are diffused in the abdominal cavity, so that the visual field of the surgery can be influenced, the surgery difficulty is increased, and measures need to be taken to discharge the smoke in the abdominal cavity in time. For example, patent document CN212234619U discloses a single smoke evacuation device for an access platform for single port laparoscopic surgery because it is not possible to evacuate smoke through an air injection valve, but it is not possible to maintain pneumoperitoneum pressure during smoke evacuation, which affects the progress of the surgery, although only the air injection valve is provided, and the problem of smoke evacuation is not considered.

Like patent document CN215534649U etc. set up gas injection valve and discharge valve on operation platform, the gas injection valve can inject carbon dioxide, and discharge valve can discharge smog, but inside discharge valve did not stretch into the abdominal cavity, and be close to the gas injection valve, and the gas of discharge valve exhaust is mostly the carbon dioxide of newly injecting, also can only discharge the smog near incision department, and the smog that is located the abdominal cavity inside can not be discharged.

In order to discharge smoke from the inside of the abdominal cavity, particularly from the deep inside of the abdominal cavity, for example, patent document CN113598970A discloses puncturing a veress needle on the abdominal wall to discharge smoke, but this method has disadvantages that it is difficult to fix the needle, the needle is liable to accidentally injure organs in the abdominal cavity, and the needle is liable to be clogged. Therefore, there is a prior art that proposes a smoke exhaust tube capable of extending into the deep inside of the abdominal cavity, for example, CN113662679A discloses a separate smoke exhaust tube, which is pulled by a magnet to be introduced into the edge of the abdominal cavity and fixed, but this method is not suitable for patients with excessive abdominal wall thickness, and when adjusting the smoke exhaust position during operation, the smoke exhaust tube may be entangled with the apparatus. Patent documents CN210130808U also include L-shaped suction pipes, and patent documents CN214907418U and CN209966582U propose plastic smoke discharge pipes which can be inserted into the deep part of the abdominal cavity and can be adjusted in angle to discharge smoke at different positions. However, the independently arranged smoke exhaust pipes extend into the abdominal cavity through the incision channels, and because the incisions are small, the smoke exhaust pipes, particularly the hard smoke exhaust pipes, can invade the access channels of the instruments, so that the moving range of the instruments is influenced; and in order to extract the smoke at different positions, the angle of the smoke exhaust pipe needs to be adjusted or the smoke exhaust pipe needs to be rotated, which in turn disturbs the apparatus. Therefore, a separate smoke evacuation tube provided through the incision tract may adversely affect the procedure.

Compared with the prior art, the invention has the following beneficial effects:

the invention is provided with a plurality of miniature smoke exhaust pipes, the smoke exhaust pipes cling to the inner wall of the incision protective sleeve to enter the abdominal cavity, the miniature smoke exhaust pipes can reduce the occupation of the internal channel of the incision protective sleeve, and the miniature smoke exhaust pipes can provide the largest possible access channel for instruments; and the smoke exhaust pipes are tightly attached to the inner wall of the incision protection sleeve, so that the interference on instruments in the incision protection sleeve can be avoided. The smoke exhaust pipe in the abdominal cavity can extend to the periphery of the incision under the traction of the expansion ring and is close to the abdominal wall, so that the smoke exhaust pipe in the abdominal cavity cannot interfere with the operation of the instrument, the smoke exhaust pipe which is diffused to the periphery can provide a larger coverage range, and smoke around the incision can be extracted simultaneously; meanwhile, the air holes of the smoke exhaust pipe are all arranged at one end close to the expansion ring, so that the smoke extracted by the smoke exhaust pipe is closer to the deep part of the abdominal cavity, and the smoke exhaust pipe can simultaneously exhaust the smoke in the abdominal cavity, particularly the deep part of the abdominal cavity.

The smoke exhaust assembly and the incision protective sleeve, the operating platform and the smoke exhaust assembly and the operating platform and the incision protective sleeve are all in the same clamping structure, so that when smoke exhaust is not needed in an operation, the smoke exhaust assembly can be omitted, and the operating platform can be directly installed on the incision protective sleeve. The clamping structure adopted among the operating platform, the smoke exhaust assembly and the incision protective sleeve can realize quick installation, and clamping can be completed only by inserting and slightly rotating; meanwhile, the invention is also provided with a lock catch for automatically locking the clamping part and preventing the clamping part from slipping.

The operating platform is provided with a plurality of instrument channels, and the instrument channels have at least two specifications and can be suitable for various minimally invasive surgical instruments such as a laparoscope lens, a suction apparatus, a separating clamp and the like. The sealing cover on the operation platform is made of soft materials, so that the inclination angle of the instrument channel can be adjusted, the moving range of the instrument can be increased, the angle of the instrument can be adjusted by a doctor according to needs when the instrument is operated, the use of the instrument is facilitated, and the operation efficiency can be improved; meanwhile, the sealing cover and the flexible film are made of transparent materials, so that a doctor can observe the internal condition of the access channel in time and observe the incision condition.

The instrument channel has self-sealing performance, is in a sealing state when the instrument is not installed, automatically seals a gap between the instrument channel and the instrument when the instrument is inserted, and automatically seals when the instrument is pulled out; the clamping part of the invention is provided with the sealing washer, so that the gap at the clamping part can be blocked to avoid internal gas leakage. The invention has good sealing performance, can avoid the influence of carbon dioxide leakage in the abdominal cavity on pneumoperitoneum pressure, and can also avoid the influence of carbon dioxide leakage in an operating room on air quality of the operating room.

The smoke exhaust device is also provided with a filter for filtering and absorbing carbon dioxide and smoke exhausted by the smoke exhaust component, so that the influence of the carbon dioxide on the air quality of an operating room due to the direct emission of the carbon dioxide into the operating room can be avoided, and the influence of the strong carcinogenic smoke on the health of personnel due to the direct emission of the strong carcinogenic smoke into the operating room can also be avoided.
