Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a novel multi-channel single-hole laparoscopic puncture device. BACKGROUND

[0002] In the existing multi-channel single-hole laparoscopic puncture device, the surgical channel is arranged on a silicone structure shaped like a breast, and the silicone structure needs to be inflated for use during surgery. During surgery, the surgeon needs to push the surgical instrument in the surgical channel forward to resist the height of the inflated silicone structure, and at the same time, the surgical instrument needs to be continuously changed in direction within the surgical channel. Since the "breast-shaped" silicone structure is soft, it is not easy to press the silicone structure, thereby making it inconvenient for surgical operation. CONTENT OF THE UTILITY MODEL

[0003] The main purpose of the present application is to provide a novel multi-channel single-hole laparoscopic puncture device, which aims to solve the above technical problems.

[0004] The technical solution adopted by the present application is as follows:

[0005] A novel multi-channel single-hole laparoscopic puncture device, comprising a base, an outer sealing sleeve of the base being provided with a fixing ring, a silicone soft body being arranged on the fixing ring, at least three surgical channels being arranged on the silicone soft body, a support cover covering the silicone soft body being buckled outside the fixing ring, and a passageway hole being arranged on the support cover for the surgical channels to pass through.

[0006] Optionally, the passageway hole corresponds to the surgical channel one by one, and the inner diameter of the passageway hole is greater than the outer diameter of the surgical channel.

[0007] Optionally, one side of the silicone soft body for connecting the surgical channels is arranged obliquely, and the inclination of the support cover matches that of the silicone soft body.

[0008] Optionally, a gas charging / discharging channel is further arranged on the outer side of the base.

[0009] Compared with the prior art, the present application has the following beneficial effects:

[0010] The novel multi-channel single-hole laparoscopic puncture device proposed in the present application discards the traditional "breast-shaped" silicone soft body, and adopts a support cover arranged outside the sheet-shaped silicone soft body. During the surgical process, the support cover provides support, which not only ensures that the inner lining silicone soft body will not deform, but also provides an additional fulcrum for the surgical operating instrument in the surgical channel, making it more convenient to apply force.

[0019] Referring to the drawings Figs. 1-2 As shown in the drawings, the embodiment of the present application provides a new multi-channel single-hole laparoscope puncture device, which comprises a base 1, the base 1 is provided with a cavity along the axial direction, for the surgical instruments to enter the abdominal cavity. The base 1 is a cylindrical shoulder structure, a fixing ring 2 is provided on the shoulder of the base 1 by adhesive connection of sealing glue, the end of the fixing ring 2 away from the base 1 forms an inclined slope, a sheet-shaped silicone soft body 3 is fixed and connected on the slope by structural glue, the silicone soft body 3 is arranged in parallel with the slope, at least three surgical channels 5 are integrally formed on the silicone soft body 3, the surgical instruments enter the abdominal cavity through the surgical channels 5, a charging / discharging channel 7 is arranged on the side of the base 1, the charging / discharging channel 7 is used to make the silicone soft body 3 full, of course, the charging / discharging channel 7 can be arranged as two independent inflation channels and deflation channels, the deflation channel is on the silicone soft body 3, and the inflation channel is on the side of the base 1. The silicone soft body 3 is further covered with a supporting cover 4, the supporting cover 4 is buckled on the fixing ring 2, the supporting cover 4 is provided with the same number of passage holes 6 as the surgical channels 5, the surgical channels 5 extend out of the passage holes 6, and the inner diameter of the passage holes 6 is greater than the outer diameter of the surgical channels 5.

[0020] Based on the above, the multi-channel single-hole laparoscope puncture device provided by the embodiment of the present application has at least the following advantages:

[0021] Firstly, the present application discards the traditional “breast-shaped” silicone soft body, adopts the fixing ring 2 to receive the silicone soft body 3, the silicone soft body 3 is covered with the supporting cover 4, the supporting cover 4 is sleeved outside the fixing ring 2 and abuts against the base 1, and the puncture device is stably placed in the puncture port by pressing the supporting cover 4 during the operation. Compared with the traditional force acting on the “breast-shaped” silicone soft body 3, the present application applies the force to the supporting cover 4, so that the silicone soft body 3 will not be denatured, and the force can be easily applied.

[0022] Secondly, the present application is provided with the passage holes 6 with a larger diameter than the outer diameter of the surgical channels 5 on the supporting cover 4, so that a gap is reserved between the surgical channels 5 and the supporting cover 4, and the medical staff can stir the surgical channels 5 during the operation, without affecting the surgical instruments to enter the abdominal cavity at different angles.

[0023] Third: Because the laparoscope in the abdominal cavity needs to simulate the visual angle of open surgery as much as possible, the traditional vertically designed surgical channel 5 will often cause the problem of uncomfortable surgical field and operation angle due to the angle limitation after the laparoscope enters the abdominal cavity, so the traditional puncture device needs to insert the surgical channel 5 into the laparoscope for observation after being bent to an inclined position, which is inconvenient for operation. The surgical channel 5 is arranged on the inclined silica gel soft body 3 in the application, so that the surgical channel 5 has a certain angle with the horizontal plane, so that the laparoscope enters the abdominal cavity from the inclined surgical channel 5, and a more comfortable surgical field and operation angle can be realized. Fourth: Because the traditional four surgical channel design causes the relatively small operable space between adjacent surgical channels, the surgical instruments will appear "squeeze" when operated inside, and the laparoscopic surgery rarely uses three surgical channels to operate at the same time, and almost never uses four surgical channels to operate at the same time. The surgical channel is designed from the traditional four to three in the application, so that the operable space between adjacent surgical channels is increased, which can effectively alleviate the "squeeze" phenomenon of surgical instruments during operation.

[0024] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
