Background

In minimally invasive human medical surgery, once a disease is found in a human body, surgery or excision is needed, in the surgery process, a puncture outfit is firstly needed to be applied, and the puncture outfit is a surgical instrument which punctures the abdominal wall and enters a body cavity channel for other surgical instruments, and belongs to a minimally invasive surgical instrument. Chinese patent document CN108309412a discloses a puncture cannula device for a laparoscopic puncture outfit, which is used for being inserted into a abdominal cavity of a patient to form a channel for a surgical instrument to pass through, and since tightness is required to be maintained in a surgical process, a double sealing structure of a comprehensive sealing valve and a duckbill sealing valve is generally provided, the comprehensive sealing valve is generally a conical elastic member, and a through hole is provided in the middle for the surgical instrument to pass through. Since a plurality of surgical instruments need to repeatedly pass through the through-hole of the integrated sealing valve during the surgical procedure, a protection device for the integrated sealing valve needs to be provided to prevent the instruments from scratching the sealing valve. The sealing valve protection device is generally arranged inside one side of the sealing valve, which is used for being inserted into a surgical instrument, as shown in fig. 1, and the existing sealing valve protection device comprises a supporting ring and a plurality of sheet bodies 2 which are arranged on the supporting ring 1 and are not provided with elastic resin materials, wherein the plurality of sheet bodies 2 are sequentially overlapped to form a protection layer along the circumferential direction of the supporting ring 1, namely, the edge positions of the adjacent sheet bodies 2 are overlapped, so that the sealing valve is completely covered in the circumferential direction on one hand, and the sheet bodies can be outwards supported to be conveniently and downwards inserted when the surgical instrument is inserted on the other hand. However, in this conventional sealing valve protection device, since the plurality of sheets are stacked in sequence, when the surgical instrument is inserted in use, the sheets easily guide the front end of the surgical instrument to the edge position where the sheets are stacked, so that the front end of the surgical instrument passes through the gap between the two sheets, and damage to the elastic sealing valve is caused after breaking through the protective layer. In addition, the structure that a plurality of lamellar bodies are laminated in proper order is inconvenient for production and processing, carries out integrated into one piece again after need carrying out accurate positioning to a plurality of lamellar bodies, and is higher to the requirement of equipment and technology.

Detailed Description

The utility model is described in further detail below with reference to the drawings and the detailed description.

As shown in fig. 2-5, the present embodiment provides a puncture outfit sealing valve protection device, which includes a support ring and a plurality of inelastic resin sheets disposed on the support ring.

The support ring comprises an inner ring 11 and an outer ring 21, wherein the outer ring 21 is sleeved on the outer side of the inner ring 11, and the inner ring and the outer ring can be mutually clamped and fixed. The sheet body comprises an inner sheet body 12 and an outer sheet body 22, the inner sheet body 12 is arranged on the inner ring 11, a plurality of inner sheet bodies 12 are circumferentially arranged to form an inner protective layer, the outer sheet body 22 is arranged on the outer ring 21, and a plurality of outer sheet bodies 22 are circumferentially arranged to form an outer protective layer.
