Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a shoulder pad and a postoperative head restriction device for radical neck dissection of oral cancer. Background Art
[0002] Oral cancer generally involves two parts of surgical operations: 1. resection of the primary focus and radical neck dissection; 2. free flap reconstruction of oral and maxillofacial defects.
[0003] In the first part of the operation, radical neck dissection and tracheotomy are required for some patients. The above operations all require a shoulder pad to fully expose the neck tissues and the anterior cervical trachea. Currently, most hospitals use overlapping cloth sheets to pad the patient's shoulders according to the required height. This method requires a large number of cloth sheets, is difficult to clean after being contaminated, is cumbersome to adjust the height, the cloth sheets are not breathable, and pressure sores are formed on the skin during long-term operations. There is an urgent need for a portable device with adjustable shoulder height to meet the shoulder padding needs of patients.
[0004] In the second part of the operation, the free flap is harvested and reconstructed after vascular anastomosis. After the operation, the free flap and the resection wound surface do not establish blood circulation and completely rely on the anastomosed arteriovenous blood vessels for blood supply. Therefore, the anastomosed arteriovenous blood vessels cannot be displaced, pulled, or folded due to the movement of the head, resulting in mechanical pressure and blood flow blockage. Especially during the high-incidence period of anastomotic vascular crisis within 72 hours after the operation, it is particularly important to accurately replicate the intraoperative body position to the postoperative period. In the past, two sandbags were used in clinical practice and placed on both sides of the patient's head to restrict the movement of the head and neck to achieve the effect of fixing the head. The sandbags are prone to displacement and cannot replicate the position where the head is restricted during the operation. When the patient moves the head slightly, the sandbags also move, losing the restrictive effect, and causing pressure sores on the auricle due to long-term compression. Therefore, there is an urgent need for a device that records the intraoperative head position and accurately replicates it for postoperative head restriction. Content of the Utility Model
[0005] In view of the above problems, a shoulder pad and a postoperative head restriction device for radical neck dissection of oral cancer are provided, aiming to solve the problems existing in the prior art.

The adjusting part includes a main body, two adjusting knobs and two sliders. Two chutes are provided on the front side surface of the main body. The two sliders are respectively arranged in the two chutes and can slide left and right along the chutes. One end of the two sliders extending out of the chutes is respectively connected to the rear ends of the two position-limiting bodies. One end of the two adjusting knobs is inserted into the chutes from the end faces of the left and right ends of the main body and penetrates through the sliders. The sliders are in threaded connection with the adjusting knobs. The adjusting knobs are rotatably connected to the main body, and the other ends of the two adjusting knobs are outside the main body.
[0011] Beneficial effects of the above solution: By rotating the two adjusting knobs, the two sliders can be driven to move along the chutes to drive the two position-limiting bodies to move.
[0012] The above-mentioned shoulder pad and postoperative head restriction device for oral cancer neck dissection also have the following characteristics. A scale for observing the position of the slider is provided on the top surface of the main body.
[0013] Beneficial effects of the above solution: It is convenient for medical staff to adjust the positions of the two position-limiting bodies and facilitate repeated positioning.
[0014] The above-mentioned shoulder pad and postoperative head restriction device for oral cancer neck dissection also have the following characteristics. The shoulder pad assembly includes a middle airbag and two shoulder pad airbags. The two shoulder pad airbags are symmetrically arranged on the front side of the middle airbag, and both the two shoulder pad airbags are communicated with the middle airbag. A lapping airbag is further arranged at the rear side of the middle airbag, and the lapping airbag is also communicated with the middle airbag.
[0015] Beneficial effects of the above solution: The lapping airbag is used to be inserted under the headrest. When the lapping airbag is inflated, the headrest and the lapping airbag repeatedly come into contact.
[0016] The above-mentioned shoulder pad and postoperative head restriction device for radical neck dissection of oral cancer also have the following characteristics: the shoulder pad airbag has a structure that is narrow in the front and wide in the back, and when the shoulder pad airbag is fully inflated, the thickness from the front end to the back end of the shoulder pad airbag gradually increases.
[0017] Advantageous effects of the above solution: The special structure of the shoulder pad airbag can effectively lift the patient's shoulders to the height required for the operation.
[0018] In summary, the advantageous effects of this solution are:
[0019] In the shoulder pad and postoperative head restriction device for radical neck dissection of oral cancer provided by the present utility model, the limiting component provided on the headrest prevents the patient's head from shifting, avoiding the influence of postoperative head shift on the patient's recovery.
