Problems solved by technology

The two sealing films are indispensable, and there is a problem with the sealing performance of one of them, which will cause the patient's pneumoperitoneum to leak during the operation, affect the operation, and even endanger the life and health of the patient
The second sealing film in the prior art, such as application number 201610619956.9, is named a trocar sealing film containing multidimensional floating folds, and application number 201610630376.X is named a trocar sealing film containing grooves , application number 201710216813.8, named trocars, sealing components and sealing films for trocars, etc., in order to solve the gaps generated when surgical instruments are inserted when they move up and down or swing left and right, most of them are set on the sealing film Wrinkle structure or rib structure, but none of the above structures can effectively avoid the generation of pores

Embodiment 1

[0014] Such as figure 1 As shown, the trocar sealing membrane provided by the present invention is entirely made of flexible materials, and the selection of materials is well known in the art.

[0015] The sealing membrane structure is composed of a cylindrical body 1 and an end diaphragm 3 connected to the end surface of the cylindrical body. The center of the end diaphragm 3 is provided with a first annular rib 4 and a second annular rib 5 with a correspondingly reduced diameter (thereby The above-mentioned annular ribs are all convex on the top and correspondingly recessed below), and the position of the second annular rib 5 is lower than the first annular rib 4 in the axial direction of the cylindrical body 1, so that the second annular rib The convex ribs are inclined towards the inside of the cylindrical body 1 as a whole, and the innermost second annular rib 5 is connected to the cone 6, and the top of the cone 6 is provided with a sealing hole 7 for the operation joyst...

Embodiment 2

[0018] Such as figure 2 , image 3 and Figure 4 As shown, a trocar sealing membrane provided by the present invention is composed of a cylindrical body 1 and an end diaphragm 3 connected to the end face of the cylindrical body. The center of the end diaphragm 3 is provided with a first annular rib 4 with a diameter corresponding to The reduced second annular rib 5, the position of the second annular rib 5 is lower than the first annular rib 4 in the axial direction of the cylindrical body 1, so that the second annular rib 5 faces toward the cylindrical body as a whole. 1 The interior is inclined, the innermost second annular rib 5 is connected to the straight cylinder 6a, and the straight cylinder 6a is connected to the cone cylinder 6b, that is, the cone 6 is composed of the straight cylinder 6a and the connected cone cylinder 6b, and the cone cylinder A sealing hole 7 is provided at the top of 6b.

Abstract

The invention relates to a puncture outfit sealing film. The puncture outfit sealing film consists of a cylindrical body (1) made of a flexible material and an end diaphragm (3) connected with the endface of the cylindrical body; a sealing hole (7) is formed in the center of the end diaphragm (3); the end diaphragm is characterized in that at least two annular convex ribs are arranged on the enddiaphragm (3); the two annular convex ribs are integrally inclined towards the inside of the cylindrical body (1); the innermost annular convex rib is connected with a conical body (6); and the sealing hole (7) is formed in the top end of the conical body (6). The beneficial effects that the annular convex ribs are additionally arranged on the sealing film of the abdominal puncture outfit, so thatductility and toughness of the sealing film are fully exerted; when a surgical instrument is inserted and moves up and down or swings left and right, the surgical instrument can be wrapped, and the sealing film can swing along with the surgical instrument, so that leakproofness and gas barrier property of the puncture outfit are ensured; and when surgical instruments with different specificationsand sizes are used for replacement, leakproofness and the gas barrier property can also be ensured, so that smooth operation of a surgery is ensured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sealing film for a surgical trocar. Background technique [0002] The main clinical purpose of the surgical trocar is to establish a channel for minimally invasive surgical instruments to enter and exit the abdominal cavity. To ensure the airtightness and gas barrier during the clinical operation, the trocar is often designed with two sealing films. The first The first sealing film is used to maintain the tightness between the abdominal puncture device and the patient's abdominal cavity when no surgical instrument is inserted or after the surgical instrument is inserted and pulled out. Maintain a tight seal between the abdominal trocar and the patient's abdominal cavity. The two sealing membranes are indispensable, and there is a problem with the sealing performance of one of them, which will cause air leakage of the patient's pneumoperitoneum during the operation,...
