Abstract

The utility model discloses an abdominal wall channel device, which comprises two tapered channel main bodies and a sealing cover, wherein the sealing cover is provided with a plurality of apparatus channels and a sealing valve. Under the condition of achieving a sealing effect, the requirement on the entrance of a plurality of apparatuses into a body cavity from a single abdominal wall cutting opening is met, and the abdominal wall channel device can be used for performing single-hole laparoscope operation in cooperation with a wrist rotating apparatus.

Description

A kind of stomach wall lane device

Technical field

This utility model relates to the Minimally Invasive Surgery apparatus, relates in particular to a kind of stomach wall lane device.

Background technology

Behind Charles Robert Richet successful implementation in 1987 the first routine laparoscopic cholecystectomy, it with the laparoscopic surgery development that the Minimally Invasive Surgery of representative experiences surplus in the of 20 year, form a relatively independent subject, derived a series of Minimally Invasive Surgerys such as thoracoscope, pelvioscope, arthroscope.At present, Minimally Invasive Surgery has become forefront, surgical operation the inside, complicated technology, and a large amount of advanced equipment, material and apparatuses at first are applied to this field, and Minimally Invasive Surgery also is an important directions of 21 century surgery development.

Minimally Invasive Surgery is meant at body surface does some perforation, endoscope and operating apparatus are entered in the body cavity by above-mentioned aperture, as abdominal cavity, thoracic cavity, pelvic cavity, articular cavity etc., by the patient under the supervision of endoscope, by hands operating apparatus outside the patient body, excise the focus of intracavity the working end that apparatus is stretched in the patient's body cavity, or to organ repair, operation such as stitching, art finishes takes out endoscope and apparatus, sews up the aperture of body surface and can finish whole surgery.

Minimally Invasive Surgery is with respect to traditional surgery, and its great advantage is that wound is little, and it is few to lose blood, and patient's post-operative recovery is fast, and distress level is lighter, and scar after the operation is not obvious etc.But Minimally Invasive Surgery still can not substitute traditional open surgery at present, and reason is: 1, the degree directly perceived in the visual field of Minimally Invasive Surgery is lower than traditional operation; 2, the motility of Minimally Invasive Surgery apparatus can not show a candle to surgical hands, can't finish complicated operations; 3, Minimally Invasive Surgery almost can't transmit the touch-pressure sensation in the operating process.Above-mentioned 3 reasons become the bottleneck of present stage Minimally Invasive Surgery development, make the development of Minimally Invasive Surgery be in sluggish state.

At present, less invasive techniques has developed the single channel laparoscopic technique, and promptly a plurality of apparatuses enter the abdominal cavity in single passage, enters and the conventional channels apparatus can only hold single apparatus, therefore develop and a kind ofly can hold the passage apparatus that a plurality of apparatuses enter the abdominal cavity, become extremely important.

Summary of the invention

The purpose of this utility model is to provide a kind of stomach wall lane device of a plurality of apparatuses of a kind of confession by single incision of abdominal wall.

In order to achieve the above object, the technical solution adopted in the utility model is:

A kind of stomach wall lane device is made up of two channel body and capping, it is characterized in that described channel body be have tapering, the cross section is semicircular barrel, channel body upper end is bigger, the outside, lower end is provided with trip; Described capping is placed in the channel body upper end of two merging, and capping is provided with several instrument channel and seal valve.

The opposite face of described two channel body is provided with tongue and groove and stuck point, and tongue and groove and stuck point were the engagement shape after two channel body merged.

Described instrument channel upper end is provided with patchhole, and the lower end is provided with two sealing lobes, and the sealing lobe is made by the thin-walled encapsulant of dome shape, and the one end is fixed on the instrument channel, and the other end is free shape.

The beneficial effect that the utlity model has is:

This device can hold a plurality of apparatuses and enter body cavity from single incision of abdominal wall, thereby satisfies the needs that the doctor carries out the single hole operation.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 2, this utility model is made up of two channel body 1 and a capping 2, two channel body 1 be have tapering, the cross section is semicircular barrel, channel body 1 upper end is bigger, the outside, lower end is provided with trip 9, two channel body 1 can be closed up into a cone, strut mutually after the trip 9 of lower end enters incision of abdominal wall, and device is fixed on the stomach wall.The face that closes up of channel body 1 is provided with tongue and groove 5 and stuck point 6, is used for two channel body 1 and is meshing with each other, and plays effect fixing and sealing.Two channel body of closing up 1 upper ends are with capping 2, and several instrument channel 3 and seal valve 4 are arranged in the capping 2, and instrument channel 3 enters usefulness in the body for operating theater instruments, and seal valve 4 is used to control intraperitoneal air pressure intensity.

As Fig. 4, Fig. 5, shown in Figure 6, capping 2 is provided with capping buckle 7, capping 2 can be fixed on two channel body 1.Instrument channel 3 upper ends in the capping 2 are patchhole 10, and the lower end is made by the thin-walled encapsulant for sealing lobe 8, sealing lobe 8, the dome shape concave surface is inside, and its basilar part is fixed on the instrument channel 3, the other end shape that dissociates, when apparatus inserted instrument channel, the sealing lobe was strutted; After apparatus took out, two sealing lobes 8 closed up and close under the anticyclonic effect in inside, play sealing function.

The above-mentioned specific embodiment is used for this utility model of explaining; rather than this utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to this utility model is made all fall into protection domain of the present utility model.
