Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a negative pressure blood-absorbing cotton swab for minimally invasive surgery. Background Technology

[0002] In minimally invasive surgery, bleeding in the surgical field or leakage of surgical irrigation fluid are common problems that affect the surgical procedure, requiring frequent use of cotton swabs, gauze, or special blood-absorbing sponges to absorb the blood.

[0003] In existing technologies, ordinary cotton swabs have a limited blood absorption capacity and need to be replaced repeatedly after they are full. This not only consumes cotton swabs and prolongs the operation time, but also results in cotton fibers falling off new cotton swabs or gauze. The operation of replacing new cotton swabs or gauze can interfere with and affect the exposure of the surgical field.

[0004] Traditional negative pressure suction devices (such as electric suction devices) are large in size and complex to operate, making them difficult to adapt to the delicate needs of minimally invasive surgery.

[0005] Therefore, we propose a negative pressure blood-absorbing cotton swab for minimally invasive surgery to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a negative pressure blood-absorbing cotton swab for minimally invasive surgery to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A negative pressure blood-absorbing swab for minimally invasive surgery includes a needle tube structure, a hollow rod structure, absorbent cotton, and an aspiration hole structure. The hollow rod structure is detachably installed at the top of the needle tube structure, the absorbent cotton is wrapped around the end of the hollow rod structure, and the aspiration hole structure is located at the end of the hollow rod structure.

[0009] Preferably, the needle structure has an integrally formed insertion short tube at the center of the top, and the hollow rod structure is fitted onto the outside of the insertion short tube.

[0010] Preferably, the inner cavity of the hollow rod structure and the inner cavity of the needle structure are interconnected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This minimally invasive surgical negative pressure blood-absorbing cotton swab, through the design and use of a hollow rod structure with suction holes, a needle structure, and the suction holes and cotton balls on the hollow rod structure, can effectively solve the problem of weak absorption capacity of current cotton swabs and the need for multiple replacements during the surgical process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a technical solution for negative pressure blood-absorbing cotton swabs used in minimally invasive surgery:

[0017] Example:

[0018] The absorbent swab mainly includes a needle structure 1 that holds the aspirated mixed liquid, a hollow rod structure 3 that is detachably installed on the top of the needle structure 1, absorbent cotton 4 at the end of the hollow rod structure 3, and an aspiration hole structure 5 for the flow of the mixed liquid at the top of the hollow rod structure 3.

[0019] The needle tube structure 1 has an integrally integrated insertion short tube 2 at its top, and a hollow rod structure 3 is fitted onto the outside of the insertion short tube 2. The hollow rod structure 3 and the absorbent cotton 4 together form a cotton swab structure. The entire cotton swab structure and the needle tube structure 1 are designed with a plug-in connection, mainly to increase the convenience of changing the cotton swab structure.

[0020] The hollow rod structure 3 has its inner cavity connected to the inner cavity of the needle structure 1. This allows the aspirated mixed liquid to be drained and stored in the inner cavity of the needle structure 1 during actual use.

[0021] In this embodiment, during minimally invasive surgery, especially when there is bleeding in the surgical field or leakage of surgical irrigation fluid, the needle structure 1 is directly manipulated to create negative pressure inside, thereby generating suction. Of course, in this technical solution, the size of the suction hole structure 5 is relatively small, so that the negative pressure inside the needle structure 1 and the hollow rod structure 3 can be maintained for a certain period of time. Then, medical staff can directly use the absorbent cotton swab to wipe away blood and irrigation fluid. During the wiping process, due to the negative pressure inside the needle structure 1 and the hollow rod structure 3, the blood and irrigation fluid absorbed on the absorbent cotton 4 can be transferred from the suction hole structure 5 and then enter the inner cavity of the needle structure 1 through the hollow rod structure 3. Therefore, the absorption capacity of the absorbent cotton 4 can be increased, that is, there is no need to replace it multiple times and waste time. After wiping and absorbing, the piston structure 6 can be pushed back appropriately for the next use.

[0022] In this technical solution, through the design and use of the hollow rod structure 3 with suction hole structure 5, the needle structure 1, and the suction hole structure 5 and cotton ball 4 on the hollow rod structure 3, the problem of weak suction capacity of cotton swabs and the need for multiple replacements can be effectively solved during the operation.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
