The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Examples
The invention is further described below with reference to the accompanying figures 1-2:
the utility model provides a leak protection gas metal puncture sheath 10, please refer to fig. 1 and 2, this leak protection gas metal puncture sheath 10 includes puncture sheath body 100 and set up in puncture sheath body 100's one-way leak protection gas subassembly 200.
The puncture sheath body 100 includes a hood 110, a metal sheath cavity 120 and a metal sheath rod 130 which are connected in sequence from top to bottom. The one-way air leakage preventing assembly 200 is disposed in the metal sheath cavity 120.
In the present embodiment, the sheath lumen 120 includes an upper connection section 121 and a lower connection section 122 that are detachably connected. Specifically, the upper connection section 121 and the lower connection section 122 are threadedly connected. In the present embodiment, the cross sections of the upper connecting section 121 and the lower connecting section 122 along the direction perpendicular to the axial line of the puncture sheath body 100 are both circular.
In this embodiment, the puncture sheath body 100 has a puncture channel (not labeled) for passing a puncture core (not shown). The one-way air leakage prevention assembly 200 includes a connection ring 210, a positioning section 220, and a plurality of gel flaps 230 for blocking the puncture channel. In this embodiment, a plurality of colloid valves 230 are sequentially and adjacently connected to the inner wall (not labeled) of the connection ring 210 along the circumferential direction of the connection ring 210. On one hand, the structure and the arrangement mode of the plurality of colloid valves 230 can be loosened downwards when the puncture core passes through, and the puncture core is recovered under the elasticity of the puncture core after being taken out, so that the puncture channel is cut off in time to avoid air leakage; on the other hand, the endoscope instrument (not shown) of the slender rod can penetrate through the sheath body and ensure air tightness, and the problems that the pneumoperitoneum pressure is insufficient and the operation visual field is not sufficiently exposed to influence the operation of an operator due to the fact that air leakage is caused by too large pipe diameter of the puncture sheath body 100 are avoided. In this embodiment, the plurality of gel flaps 230 are arranged in a shingled manner to further improve air tightness.
In this embodiment, the one-way air leakage preventing assembly 200 is detachably connected to the metal sheath cavity 120. Specifically, the connection ring 210 is clamped to the puncture sheath body 100. More specifically, in the present embodiment, the connection ring 210 is sleeved on the lower connection section 122, and the upper connection section 121 is sleeved on the connection ring 210. The connection ring 210 can be merely caught on the lower connection section 122 during the process of screwing the upper connection section 121 to the lower connection section 122.
In the present embodiment, the cross-section of the positioning section 220 along the axis perpendicular to the puncture sheath body 100 is circular. The positioning section 220 has one end connected to the connection ring 210 and the other end extending toward the lower connection section 122. The outer diameter of the positioning section 220 is equal to the inner diameter of the lower connecting section 122. The positioning section 220 is provided to further help the one-way air leakage prevention assembly 200 to be better mounted to the puncture sheath body 100.
In the present embodiment, in order to further improve the airtightness, the hood 110 of the puncture sheath body 100 is provided with a cross-shaped communication hole 111. The cross-shaped communication hole 111 can be more beneficial to the attachment of the slender rod endoscope apparatus, and the air tightness is further improved on the basis of the one-way air leakage prevention assembly 200.
In the present embodiment, the metal sheath rod 130 of the puncture sheath body 100 is provided with the non-slip thread 131. The anti-slip screw 131 is provided along the length direction of the metal sheath rod 130. The anti-slip thread 131 can increase the friction force of the metal sheath rod 130, and prevent the puncture sheath from slipping in the operation process.
The air leakage preventing metal puncture sheath 10 provided in the present embodiment is used as follows: the one-way air leakage preventing assembly 200 is mounted on the puncture sheath body 100, and the puncture core or the endoscope instrument can pass through the puncture channel to perform laparoscopic surgery. When the puncture core or the endoscope apparatus passes through the puncture channel, the colloid valve 230 faces downwards, and when the puncture core or the endoscope apparatus is taken out, the colloid valve 230 recovers and cuts off the puncture channel under the action of the self elasticity to improve the air tightness.
In summary, the air leakage preventing metal puncture sheath 10 provided by the embodiment of the present invention does not use a metal gasket, and can improve the air tightness of the puncture sheath when using the slender rod endoscope apparatus without using a converter; the gas tightness is good, the operation of doctors is convenient, and the operation process can be accelerated.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
