Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a multi-channel single-hole puncture device with large-angle swing. Background Art

[0002] With the advancement of medical technology, minimally invasive surgical procedures using laparoscopic techniques are becoming increasingly popular in China. Currently, most single-port trocars on the market have relatively short instrument channels, which limits the instrument's swing range during surgery, hindering the operator's operation and increasing the difficulty of the procedure, which, to a certain extent, affects the surgical progress. For breast surgery via the axillary region, the existing channels are limited in their swing angle, as the opening is far from the surgical site. This makes it impossible to achieve large swings during the procedure, making them unsuitable for this procedure. Summary of the Invention

[0003] The purpose of the utility model is to provide a multi-channel single-hole puncture device with a large swing angle, which satisfies the multi-directional swing of the instrument during the operation.

[0004] The utility model is realized by the following technical solutions: a multi-channel single-hole puncture device with large swing angle, comprising a sealing component and an insertion component; the sealing component and the insertion component are connected in a detachable manner;

[0005] The sealing assembly includes a plurality of instrument channels, a ventilation assembly and a sealing body; the instrument channels and the ventilation assembly are installed on the top surface of the sealing body;

[0006] Among the multiple instrument channels, at least one instrument channel is a short instrument channel with a shorter length, and the remaining instrument channels are long instrument channels with a longer length.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. The utility model is provided with a long instrument channel above the sealing body to meet the multi-directional swing of the instrument during the operation and improve the operational flexibility of the instrument during the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Explanation of reference numerals: 1 sealing assembly, 11 instrument channel, 111 short instrument channel, 112 long instrument channel, 12 ventilation assembly, 13 sealing body, 14 connector buckle, 2 insertion assembly, 21 channel film, 22 external clamping ring, 23 insertion ring, 24 lifting strap. DETAILED DESCRIPTION

[0012] The present invention is described in detail below with reference to the accompanying drawings, but the protection content of the present invention is not limited to the following:

[0013] like Figure 1-2 As shown: A multi-channel single-hole puncture device with a large swing angle, which includes a sealing component 1 and an insertion component 2; the sealing component 1 and the insertion component 2 are connected in a detachable manner;

[0014] The sealing assembly 1 includes multiple instrument channels 11, a ventilation assembly 12 and a sealing body 13; the instrument channels 11 and the ventilation assembly 12 are installed on the top surface of the sealing body 13; among the multiple instrument channels 11, at least one instrument channel 11 is a short instrument channel 111 with a shorter length, and the remaining instrument channels 11 are long instrument channels 112 with a longer length.

[0015] The insertion assembly 2 is a conventional structure, primarily comprising a channel membrane 21, outer retaining rings 22 at either end of the membrane, and an insertion ring 23. The insertion ring is equipped with a lifting strap 24, and the outer retaining ring is mated with a sealing body. During use, the insertion ring is placed into the cavity through the incision. The height of the channel membrane is adjusted to match the tissue thickness by flipping the outer retaining ring. The sealing assembly is then removed, the outer retaining ring is connected to the sealing body, and confirmation is confirmed. The inflator is connected to the ventilation assembly, the remaining ventilation components are closed, and the sealing assembly is saturated by inflation. The surgical instruments are then introduced into the cavity through the instrument channel, and the surgical procedure is then performed.

[0016] The overall operation of the present invention is similar to that of existing multi-channel, single-hole trocars. Structurally, the instrument channel and sealant are integrally formed, typically made of soft silicone. The primary difference between the present invention and existing multi-channel, single-hole trocars is that the instrument channel on the sealant is divided into a short instrument channel 111 and a long instrument channel 112. The short instrument channel 111 serves as an entry and exit passage for shorter instruments during surgery, while the long instrument channel 112 is suitable for most surgical instruments and, due to its length, facilitates multi-directional swinging of the instruments during surgery.

[0017] The length of the short instrument channel 111 ranges from 30 to 50 cm; the length of the long instrument channel 112 ranges from 90 to 120 mm.

[0018] The end of the instrument channel 11 is provided with a connector buckle 14 for connecting to a surgical instrument.

[0019] Although the present invention is illustrated and described using specific embodiments and their alternatives, it should be understood that various changes and modifications can be implemented without departing from the spirit and scope of the present invention. Therefore, it should be understood that the present invention is not limited in any sense except by the appended claims and their equivalents.
