[0002] Surgical puncture devices can be used in various minimally invasive surgical operations. They are used by specialists to puncture the abdominal cavity, deliver gas into the abdominal cavity, and establish a channel for endoscopes and surgical instruments to enter and exit the abdominal cavity from the outside during laparoscopic surgery. Various laparoscopic surgeries, including minimally invasive surgical surgeries, minimally invasive gynecological surgeries, thoracic surgery, urological surgery and other laparoscopic surgeries, can be matched with various laparoscopic television systems at home and abroad. However, the puncture devices in the prior art use disposable soft plastic packaging. Since the soft plastic packaging material has no supporting function, the needle tip of the puncture needle is at risk of being hit by external force. On the one hand, it is easy to cause the needle tip to be injured and damage the puncture device. On the other hand, the soft plastic packaging is at risk of being punctured by the needle tip of the puncture needle and the tip of the cannula.

[0022] In the figure: a protective seat body 1, a first sleeve hole 2, a second sleeve hole 3, an arc bottom 4, a slope 5, an elastic locking member 6, an observation hole 7, a deformation buffer through hole 8, a weight reduction groove 9, and a reinforcing rib plate 10. DETAILED DESCRIPTION
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Combination Figure 1 and Figure 2 As shown, a needle protection device for a puncture device comprises a protection seat body 1, wherein the upper surface of the protection seat body 1 is provided with a first sleeve hole 2 for accommodating the end of the puncture device sleeve and a second sleeve hole 3 for accommodating the end of the puncture device needle rod, wherein the first sleeve hole 2 and the second sleeve hole 3 are both recessed into the protection seat body 1 to form a structure with one end open and the other end closed, and the inner diameter of the first sleeve hole 2 is larger than the inner diameter of the second sleeve hole 3
[0025] When the utility model is used, the puncture device is separated into two parts, the puncture device sleeve and the puncture device needle rod, and then the puncture device sleeve and the puncture device needle rod are respectively inserted into the first sleeve hole 2 and the second sleeve hole 3. Therefore, the utility model provides a needle protection device specially used for the puncture device, which can accommodate the ends of the puncture device sleeve and the puncture device needle rod by using the first sleeve hole 2 and the second sleeve hole 3 provided on the protection seat body 1, thereby protecting the tip of the puncture device from being damaged by external force collision, and preventing the tip of the puncture device from puncturing the soft plastic package.
[0026] Preferably, the bottoms of the first sleeve hole 2 and the second sleeve hole 3 are both provided with arc-shaped arc bottoms 4, and one side of the bottom of the first sleeve hole 2 is also provided with an inclined surface 5, and the inclined surface 5 is connected to one end of the arc bottom 4. In this way, it can better fit the end of the puncture sleeve and the puncture needle rod.
[0027] Combination Figure 1 and Figure 2As shown, the first sleeve hole 2 and the second sleeve hole 3 are provided with an elastic locking member 6 for locking the sleeve of the puncture device or the needle rod of the puncture device at one end close to the opening. The elastic locking member 6 is fixed on the inner wall of the first sleeve hole 2 and the second sleeve hole 3, and the elastic locking member 6 is connected end to end in a ring shape. The ring-shaped elastic locking member 6 is deformed after being compressed, thereby fastening the side of the sleeve of the puncture device or the needle rod of the puncture device.
[0028] like Figure 1 As shown, the side of the protection seat body 1 is also provided with a plurality of observation holes 7, and the observation holes 7 are connected with the first sleeve hole 2 or the second sleeve hole 3. The utility model provides the observation holes 7 on the side of the protection seat body 1, so that the insertion position of the puncture sleeve and the end of the puncture needle rod can be observed during use, and at the same time, the materials used in the manufacture of the protection device 1 can be reduced, and the friction force of the puncture when inserted can be reduced, so as to facilitate its insertion and removal.
[0029] like Figure 2 As shown, the protection seat body 1 is made of rubber material and also includes a deformation buffer through hole 8 arranged in the protection seat body 1 and located between the first sleeve hole 2 and the second sleeve hole 3. The deformation buffer through hole 8 extends along the length direction of the first sleeve hole 2 and the second sleeve hole 3. One end of the deformation buffer through hole 8 is closed, and the other end passes through the upper end surface of the protection seat body 1.
[0030] The protective seat body 1 is made of rubber material, for example, TPE material. This material has good elasticity, and after the insertion of the puncture tube and the puncture needle rod, a certain elastic deformation will occur, thereby playing a role of tightly wrapping. A deformation buffer through hole 8 is provided between the first sleeve hole 2 and the second sleeve hole 3, so that the deformation buffer through hole 8 can be squeezed to facilitate the deformation of the puncture tube and the puncture needle rod after insertion, so as to facilitate smooth insertion.
[0031] Preferably, the inner diameter of the deformation buffer through hole 8 gradually decreases from one end close to the upper end surface of the protection seat body 1 to the other end.
[0032] like Figure 1 As shown, the protection seat body 1 is symmetrically provided with weight-reducing grooves 9 on both sides, the weight-reducing grooves 9 are recessed into the protection seat body 1, and a plurality of reinforcing ribs 10 are also provided in the weight-reducing grooves 9, and the two ends of the reinforcing ribs 10 are fixedly connected to the protection seat body 1. In this way, the overall material of the protection seat body 1 can be further reduced, while ensuring that the protection seat body 1 has a certain mechanical strength.
[0033] Preferably, four reinforcing ribs 10 are arranged in each weight-reducing groove 9, and the reinforcing ribs 10 are parallel to each other. In this way, the reinforcing ribs 10 can generate reinforcing forces that are parallel to each other, so that a larger resultant force can be obtained.
[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0035] Although the present invention uses more terms such as protective seat body 1, first sleeve hole 2, second sleeve hole 3, arc bottom 4, inclined surface 5, elastic locking member 6, observation hole 7, deformation buffer through hole 8, weight reduction groove 9, reinforcing rib plate 10, etc., it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
