Embodiment 1

[0046] like Figure 1-2 Shown is a surgical device (laparoscopic surgical device) according to an embodiment of the present invention. The surgical device includes a sealing cover body 100 and an incision protection sleeve 200 , and the sealing cover body 100 and the incision protection sleeve 200 are detachably connected. Thus, the incision protector 200 can be inserted into the surgical incision according to needs during the operation, and then the sealing cover 100 and the incision protector 200 are connected together, and the incision protector 200 is inflated through the sealing cover 100 to make the operation The incision or the tissues or organs in the surgical incision are stretched to facilitate the observation of the operator. In addition, the surgical device forms a relatively airtight cavity, and the operator can also insert surgical instruments through the airtight cover 100. The surgical instruments are operated in a relatively airtight and isolated cavity, whic...

Embodiment 2

[0060] The difference between embodiment 2 and embodiment 1 is: as Image 6 As shown, the gas baffle 15 includes a connecting seat 153 , a first sealing valve 154 and a second sealing valve 155 . The connecting seat 153 is cylindrical, and the first sealing valve 154 and the second sealing valve 155 are arranged on the upper end of the cylindrical connecting seat 153 ( Image 6 upper right in ). The upper end of the connection seat 153 is provided with a first detachable connector, which is an external thread in this embodiment. Correspondingly, the bottom of the passage liner 122 is provided with an internal thread. Detachable connection between plate 15 and channel liner 122 . In other embodiments, the detachable connection between the air blocking baffle 15 and the channel liner 122 can also be achieved by clipping, socketing or bonding.

[0061] The first sealing valve 154 and the second sealing valve 155 jointly block the lower end of the connecting seat 153 (lower lef...

Embodiment 3

[0064] like Figure 7-8As shown, it is a cut protection sleeve 200 used in conjunction with the above-mentioned sealing cover 100 . The incision protector 200 includes a channel 22, a connecting ring 21 and an implant ring 23, wherein the connecting ring 21 is arranged at the top of the channel 22 for connecting the connection port 14 of the sealing cover 100, and the implant ring 23 is arranged at the channel 22 The bottom end of the implant ring 23 is used for implanting in the surgical incision. With the help of the shaping and abutting effect of the implant ring 23, it can ensure that the shape of the implant ring 23 is relatively constant and will not be deformed due to tissue extrusion; It can ensure that the implant ring 23 abuts against tissues or organs, and ensures that the interior of the surgical device is relatively airtight.

[0065] As a preferred embodiment, the incision protector 200 is an incision protector made of transparent or translucent flexible materia...

Abstract

The invention discloses a sealing cover which comprises a shell and an instrument channel and an air inlet channel which are arranged at the top of the shell. The bottom of the shell is provided witha connector for being connected with an incision protective sleeve. The instrument channel and the air inlet channel are both communicated with the interior of the shell; a sealing cap is arranged atthe top of the instrument channel, a through hole is formed in the sealing cap, and the instrument channel is communicated with the exterior through the through hole; the sealing cover further comprises an air blocking baffle, and the air blocking baffle is used for blocking communication between the instrument channel and the shell; when a surgical instrument is inserted into the through hole, the surgical instrument is in clearance fit with the through hole, and when the surgical instrument continues to stretch into the shell through the instrument channel, the air blocking baffle is stressed to be opened. The invention further discloses an incision protective sleeve and an operation device. The sealing cover has the advantages of being low in infection rate, enabling operating personnelto insert surgical instruments to perform operation and the like.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and in particular to a sealed cover. The present invention also relates to an incision protector. The present invention also relates to a surgical device assembled by the above-mentioned sealed cover and the incision protector. Background technique [0002] Multi-channel single-hole laparoscopic trocars are often used in laparoscopic surgery for various resections. In one operation, multiple single-hole laparoscopic trocars are often required. The existing technology has the problem of cumbersome operation or lack of airtightness after connection, and the complications caused by incision infection also make it difficult for doctors. In 2011, the Ministry of Health issued the "Administrative Measures for Antimicrobial Drugs in Medical Institutions", which made strict regulations on the use of antibiotics in hospitals, and put forward higher requirements for how to control infectio...
