Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head fixing auxiliary device for puncture. Background Art

[0002] Internal jugular vein catheterization is a very common operation in central venous catheterization. Its purpose is to place an indwelling catheter into the internal jugular vein to facilitate short-term intravenous medication or as a temporary vascular access for extracorporeal circulation therapy. During deep vein puncture, the patient usually remains in a supine position with the head turned to the opposite side to expose the neck to be punctured. Then, ultrasound positioning is performed and the puncture point is marked. The operating doctor disinfects the puncture site and then lays a disinfectant towel. Usually, the disinfectant towel will cover the patient's head, leaving only an operating hole. After the puncture tools are prepared, the puncture can be performed.

[0003] During the puncture process, the patient's head needs to be fixed to one side, which will cause neck discomfort over time. Coupled with the discomfort caused by the puncture, the patient is prone to physiological shaking. The existing technology generally cannot effectively fix the patient's head, which can easily affect the doctor's operation and the puncture surgery being performed. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.

[0033] A head fixing auxiliary device for puncture provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Combination Figure 1-5 As shown, the utility model provides a head fixation auxiliary device for puncture, including a puncture operating bed 100, on which a head fixation mechanism 200 and an adjustment mechanism 300 are arranged. The puncture operating bed 100 is mainly used to facilitate the patient to lie flat for venous puncture. The head fixation mechanism 200 and the adjustment mechanism 300 can keep the patient's head at a relatively comfortable angle when puncturing the internal jugular vein, and then limit and fix it to prevent the patient from affecting the puncture process due to unexpected movements.

[0036] The head fixing mechanism 200 includes an adjusting disk 201 rotatably connected to the puncture operating bed 100, a base 202 arranged on the adjusting disk 201, a fixing groove 208 is provided on the top of the base 202 for convenient placement of the patient's head, a support rod 203 connected to the base 202, a guide rod 204 movably connected to the support rod 203, a fixing plate 205 fixedly connected to the guide rod 204, a protective pad is provided on the side wall of the fixing plate 205 for convenient protection of the patient, a threaded rod 206 rotatably connected to the fixing plate 205, a threaded hole matching the threaded rod 206 is provided inside the support rod 203, and a turning handle 207 fixedly connected to the top of the threaded rod 206.

[0037] It should be noted that there are two guide rods 204, and a through hole compatible with the guide rod 204 is opened inside the support rod 203. The set guide rod 204 can not only guide the fixed plate 205 when it moves, but also prevent it from rotating with the threaded rod 206.

[0038] Furthermore, the fixing plate 205 is in an arc shape, and is movably connected to the threaded rod 206 via a bearing. Rotating the threaded rod 206 drives the arc-shaped fixing plate 205 to move up and down, so that it can adapt to the heads of different patients.

[0039] Specifically, when performing the puncture operation on the patient, the patient is first made to lie on the puncture operating bed 100, with the patient's head placed in the fixing groove 208, and then the handle 207 is turned to drive the threaded rod 206 to rotate, and the threaded rod 206 drives the fixing plate 205 to move downward to press and fix the patient's head, so as to prevent the patient from moving abnormally due to discomfort during the puncture process, which may affect the puncture operation.

[0040] Embodiment 2:

[0041] Combination Figure 1-5 As shown, in the above embodiment, the adjustment mechanism 300 includes a connecting rod 301 fixedly connected to the adjustment disk 201, a storage box 302 fixedly connected to the connecting rod 301, a pull rod 303 movably connected inside the storage box 302, a through hole adapted to the pull rod 303 is opened inside the connecting rod 301 to facilitate the up and down movement of the pull rod 303, a limiting tooth 304 connected to the bottom of the pull rod 303, a baffle 305 fixedly connected to the pull rod 303, and an elastic member 306 connected to the baffle 305, one end of the elastic member 306 is connected to the baffle 305, and the other end is connected to the storage box 302. The elastic member 306 is used to facilitate the pull rod 303 to be reset, an arc groove 307 opened on the puncture operating bed 100, and teeth 308 arranged inside the arc groove 307, and the limiting tooth 304 and the teeth 308 are meshed with each other.

[0042] Specifically, by pulling the pull rod 303 to drive the limit tooth 304 to move upward, the adjustment disk 201 can be unlocked, so that it drives the entire head fixing mechanism 200 to deflect left and right, so that the patient can adjust the puncture position to a relatively comfortable position according to his own situation, avoiding long-term fixed position, which may cause muscle soreness, shortness of breath and many other discomforts to the patient. After the adjustment, the pull rod 303 is released, and the limit tooth 304 is driven by the elastic force of the elastic member 306 to be stuck in the gap between the teeth 308, and the adjustment disk 201 can be locked again.

[0043] The working principle and use process of the utility model are as follows: first, the patient lies on the puncture operating bed 100 and places the patient's head in the fixing groove 208, then the turning handle 207 is turned to drive the threaded rod 206 to rotate, and the threaded rod 206 drives the fixing plate 205 to move downward to press and fix the patient's head, then the pull rod 303 is pulled to drive the limit tooth 304 to move upward, and the adjusting disk 201 is unlocked, and the patient is allowed to adjust the puncture position to a relatively comfortable position by rotating the adjusting disk 201, and then the pull rod 303 is released, and the adjusting disk 201 is locked again, so that the patient can perform the puncture operation in a relatively comfortable state.
