Description

Sealing gasket of laparoscope puncture outfit

Technical Field

The utility model is applied to the technical field of surgical medical instruments, and particularly relates to a sealing gasket of a laparoscopic puncture outfit for minimally invasive medical operations.

Background

The laparoscopic puncture outfit is applied to minimally invasive medical operations, and pneumoperitoneum needs to be established in the abdominal cavity of a human body. The pneumoperitoneum is an important condition of the laparoscopic surgery, and under the condition of sufficient pneumoperitoneum, the pneumoperitoneum can prop open the abdominal wall to increase the distance between the abdominal wall and the visceral organs and also prop open the distance between the visceral organs, so that a relatively wide visual field and an easily operated operation space are provided for a surgeon performing the surgery, and the laparoscopic puncture outfit consists of a puncture rod assembly, a sealing assembly and a puncture cannula assembly. In the prior art, a sealing gasket of a sealing assembly is formed by alternately stacking a single sealing gasket or four same thin rubber sealing gaskets, and the sealing assembly has the following defects: 1) the structure of the single-sheet sealing gasket is in an integrally closed conical shape, the diameter of the central hole is in a fixed size, and when medical instruments with different diameters penetrate through the sealing gasket, the insertion and extraction forces are different. When inserting large diameter medical instruments, the insertion and extraction forces are excessive. When inserting a small diameter medical instrument, the insertion and extraction force is too small. And the probability of breakage of the sealing gasket is increased in the process of inserting and pulling the surgical instrument. This affects the operation of the surgeon. 2) The sealing element is formed by overlapping four same sealing gaskets in a staggered mode, the structure cannot completely seal the overlapped part, and a part of gas leakage happens. Moreover, the structure is difficult and time-consuming to produce and assemble, and is difficult to realize automatic production.

Because the sealing assembly has the defects, the problems of unstable operation, unreliable sealing and unstable pneumoperitoneum pressure of an operation passage exist in the operation process, the structural design is complex, and the ideal operation effect cannot be achieved.

The present invention has been made in view of the above circumstances.

Disclosure of Invention

In order to overcome the problems in the prior art, the utility model provides the sealing gasket of the laparoscopic puncture outfit, which adopts the upper and lower superposition of single thin rubber sealing gaskets, and the thin rubber sealing gaskets are superposed up and down in use, so that the sealing effect is good; and the installation is convenient, and the manufacturing cost is low.

In order to achieve the purpose, the utility model adopts the technical scheme that: a sealing gasket of a laparoscope puncture outfit comprises a thin wall and a lug, wherein the outer edge of the thin wall is connected to the inner side of the lug, and the thin wall and the lug are spirally distributed with the center.

Further, the rotation angle of the thin wall and the lug is greater than 360 degrees.

Further, the thin wall is conical with a low center and high periphery.

Further, the lug is arranged on the top outer side of the thin wall.

Optionally, the lug is provided with a mounting hole for fixing the sealing gasket on the puncture outfit.

Further, the mounting hole on the lug is multiple.

Furthermore, the thin wall is made of rubber or nontoxic thermoplastic elastomer.

The utility model has the advantages that: 1. the sealing effect of the single-sheet sealing gasket is good; 2. the sealing gasket is convenient to install; 3. the operation hand feeling of the doctor is good in the using process.

Detailed Description

The sealing gasket of the laparoscopic puncture outfit for minimally invasive medical surgery according to the present invention will be further described with reference to the accompanying fig. 1-2. The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

As shown in FIG. 1, the packing for a laparoscopic puncture instrument according to the present invention comprises a thin wall 10 and a lug 20, wherein the thin wall 10 has a spiral conical shape, the outer edge thereof is connected to the inner side of the lug 20, and the packing 30 is stacked up and down to form a through hole in the central region thereof. The through hole is used for penetrating through the puncture core of the puncture outfit so as to facilitate the puncture core to enter the abdominal cavity of a patient.

The gasket may have a flat planar shape or a conical shape which is slightly tapered, and preferably, the thin wall 10 has a conical shape with a low center and high periphery, so that the gasket can be attached and sealed better after being stacked one on top of the other.

When the thin wall 10 assumes a thin planar shape, the lugs 20 are disposed outside the thin wall 10; when the thin wall 10 presents a thin cone shape, the lugs 20 are arranged outside the top of the thin wall 10. The purpose of the lugs 20 is to facilitate the sealing of the seal on the puncture instrument.

The lug 20 is provided with a first mounting hole 21 for receiving a fixing screw, rivet or pin for fixing the seal to the puncture instrument. The lugs 20 have a plurality of mounting holes 21, such as 6, 8, 10, 12, 16 or even more.

As shown in FIG. 2, the sealing gasket 30 of the laparoscopic puncture outfit provided by the present invention comprises a single sealing gasket, wherein the thin walls 10 are stacked one on top of another, and the lugs 20 are stacked one on top of another, the sealing gasket 30 can keep the puncture outfit airtight during the minimally invasive laparoscopic medical surgery, and ensure the good operation feeling of the surgeon, thereby enabling the minimally invasive surgery to be smoothly performed.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
