Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of puncture needles, in particular to a protective sleeve for a puncture needle after hepatobiliary surgery. Background Art
[0002] At present, during hepatobiliary surgery, puncture needles are frequently used medical devices, and their main purpose is to be used for infusion. Currently, puncture needles are mainly steel needles with a long length. Injections are performed on the liver and gallbladder through the puncture needle head. After the operation, the puncture needles need to be recovered, disinfected, cleaned, and then sterilized, etc., so that they can be used again. However, during the storage and protection of the puncture needles, especially the long puncture needles, they need to be stored separately to avoid breakage and deformation during storage. The existing storage is accommodated by a closed tube body, and the tube body is put on the puncture needle for protection. However, it is particularly inconvenient to take the puncture needle, and a large space and stroke are required to pull the puncture needle out of the tube body, which is inefficient and inconvenient to operate.
[0003] The existing puncture needle protective cover is difficult to protect the needle head of the puncture needle body during use, resulting in collision or external factors during storage, causing damage to the needle head of the puncture needle body. In addition, it is difficult to limit the puncture needle body during storage, resulting in the puncture needle body falling off during storage and causing damage. Based on this, the utility model designs a post-operative puncture needle protective cover for hepatobiliary surgery to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-6 , the utility model provides a technical solution:
[0027] A postoperative puncture needle protective sleeve for hepatobiliary surgery comprises a protective sleeve body 1, a puncture needle body 4, an adjustment mechanism and a limiting mechanism, wherein the adjustment mechanism comprises a rotating block 501, a rotating block 501 is arranged at the bottom of the protective sleeve body 1, a threaded rod 502 is installed inside the protective sleeve body 1, one end of the threaded rod 502 passes through the protective sleeve body 1 to the outside of the protective sleeve body 1 and is connected to the rotating shaft of the rotating block 501, and a movable plate 503 is installed outside the threaded rod 502; the movable plate 503 can be adjusted by the coordinated use of the rotating block 501 and the threaded rod 502.
[0028] The limiting mechanism includes an arc plate 301, and the arc plate 301 is installed at one end of the protective cover body 1 away from the rotating block 501. A plurality of Velcro strips 302 are symmetrically installed on the outside of the arc plate 301, and an adhesive plate 303 is installed on the outside of the protective cover body 1. The coordinated use of a plurality of Velcro strips 302 can limit the puncture needle body 4, and the Velcro strips 302 are bonded to the outside of the adhesive plate 303 when not in use;
[0029] The outside of the movable plate 503 is installed with an adsorbent cotton 504, the end of the threaded rod 502 away from the rotating block 501 is installed with a circular baffle 505, the outside of the protective cover body 1 is installed with an indicator plate 201, and the outside of the protective cover body 1 is also installed with an anti-slip cover 202. The indicator plate 201 records the puncture needle body 4 placed inside the protective cover body 1, and the anti-slip cover 202 plays an anti-slip role;
[0030] Several limiting rings 203 are symmetrically installed inside the protective cover body 1, and through grooves 204 are opened inside the limiting rings 203. The limiting ring 203 located at the top of the protective cover body 1 limits the puncture needle body 4, and the protective cover body 1 is a circular tubular structure. The circular structure can better protect the puncture needle body 4. The limiting ring 203 is made of silicone material, and the size of the through groove 204 is larger than the tube body of the puncture needle body 4. The limiting ring 203 protects the tube body of the protective cover body 1.
[0031] When the operation is completed and the puncture needle body 4 needs to be stored, the staff holds the anti-slip cover 202 and puts the puncture needle body 4 into the protective cover body 1 through the arc plate 301. At this time, the needle tube of the puncture needle body 4 enters the protective cover body 1 through the through groove 204. The limiting ring 203 installed inside the protective cover body 1 can protect the needle tube of the puncture needle body 4, and the limiting ring 203 located at the top of the protective cover body 1 supports the puncture needle body 4;
[0032] After the puncture needle body 4 is inserted, the needle head of the puncture needle body 4 needs to be protected to avoid damage. The rotating block 501 is rotated, and the rotating block 501 drives the threaded rod 502 to rotate. The threaded rod 502 drives the movable plate 503 to adjust up and down during the rotation process. The movable plate 503 is adjusted to a suitable height. At this time, the needle head of the puncture needle body 4 is protected by the adsorption cotton 504. The adsorption cotton 504 can absorb the blood remaining on the outside of the puncture needle body 4 to prevent the blood on the outside of the puncture needle body 4 from contaminating the inside of the protective cover body 1 (the protective cover body 1 needs to be disinfected as a whole after use, and the adsorption cotton 504 needs to be replaced after use to avoid cross infection);
[0033] After the needle tip of the puncture needle body 4 is protected, the puncture needle body 4 needs to be limited. The Velcro 302 is removed from the outside of the adhesive plate 303. The puncture needle body 4 can be limited by using a plurality of Velcro 302 in conjunction with the limiting ring 203. After the puncture needle body 4 is limited, the type of the puncture needle body 4 is written on the outside of the indicator 201, so that medical staff can know the puncture needle body 4 placed inside the protective cover body 1.
