Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a head and neck surgery cavity traction device. Background Art

[0002] The head and neck surgical cavity refers to the cavity space formed in the head and neck tissue during head and neck surgical procedures for operating and removing lesions. In order to create the cavity space, traction devices are used to pull away the surrounding tissues of the surgical site to form the cavity space.

[0003] Transoral endoscopic thyroid surgery is a type of head and neck surgery. During transoral endoscopic thyroid surgery, the patient's head and shoulders must be restrained under anesthesia to prevent changes in body position due to muscle relaxation and to prevent changes in body position during the operation, which may lead to displacement of the surgical cavity. Currently, a fixed belt is usually used to restrain the patient's shoulders. The belt is wrapped circumferentially in the vertical plane, binding the patient's chest and shoulders to the bed. The tightness of the belt and the patient's skin condition must be checked every 30 minutes during the operation to prevent pressure sores or nerve damage. Then, a cavity space is created by a traction piece. Specifically, the traction piece includes a retractor and a support frame. The support frame is connected to the operating table. The retractor is inserted from the incision in the patient's mouth and extends into the patient's neck. The retractor is connected to the support frame to shorten the distance between the retractor and the support frame. The retractor props up the patient's epidermal tissue, and the doctor then performs surgery in the space opened by the retractor.

[0004] Before the operation, multiple operations are required to limit the patient's head and shoulders and create cavity space, which is a cumbersome operation. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a head and neck surgery cavity traction device that can limit the patient's head and shoulders, and can also be used to create cavity space and reduce the number of operating steps.

[0006] The technical solution adopted by the present invention is as follows: a head and neck surgical cavity traction device, including a traction member for pulling the surgical cavity, and also including a first support member for supporting and limiting the patient's head, and two second support members respectively located on the sides of the first support member. The two second support members are used to provide support for the traction member. The second support member is connected to the first support member and can be slidably matched. After the second support member slides, the second support member is fixedly connected to the first support member. The second support member abuts against the patient's shoulders and drives the traction member to slide to the patient's shoulder-clavicular area.

[0007] Principle of the technical solution: During the operation, the patient lies in a supine position (head high and feet low). The patient's head is placed on the first support member. The second support member is slidably engaged with the first support member. The second support member abuts against the patient's shoulders. After the second support member slides, it is fixedly connected to the first support member. The position of the second support member is fixed. When the patient's head is placed on the first support member, the head and the first support member limit each other. At this time, the second support member also abuts against the patient's shoulders, that is, the second support member limits the patient's shoulders. At this time, the patient's head and shoulders are both limited, so that the patient's neck can be straightened and kept stable. The second support member provides support for the traction member and drives the traction member to be located in the patient's acromioclavicular region (the region between the two shoulders and the collarbone).

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) The first support member can provide support and limitation for the patient's head. When the patient's head is located on the first support member, the patient's head also limits the first support member. It can also be used to set the second support member and connect and limit the second support member; 2) Compared with using a restraint belt to restrain the patient's shoulders, it is necessary to regularly check the restraint situation of the patient during the operation. After the second support member is slidably engaged with the first support member, it can limit the patient's shoulders without the need to additionally use a fixing belt to limit the patient's shoulders. The patient's shoulders are opened, reducing the compression area on the patient's body, thereby avoiding pressure sores or nerve damage. There is no need to regularly check the restraint situation of the patient. Moreover, when using a restraint belt to restrain the patient's shoulders, two people need to cooperate in the operation. The two people stand on both sides of the hospital bed respectively, and let the restraint belt wrap around the patient's shoulders. The present invention does not require multiple people to cooperate in the operation, and the operation is convenient; 3) At the same time, the patient's shoulders also cooperate with the first support member to limit the second support member, so that the position of the second support member is fixed to provide support for the traction member, and there is no need to set up and install a connection seat connecting to the hospital bed for the traction member, reducing the steps of installing the connection seat and saving materials; 4) The second support member is slidably engaged with the first support member, and it can also be used to limit the shoulders of patients with different neck lengths, with a wide range of applications. At the same time, it also assists in limiting the patient's neck, keeping the patient's neck in a stretched state, that is, limiting the patient's head, neck and shoulders at the same time, and can also provide support for the traction member.

[0009] As a preferred embodiment of the present invention, the first support member includes a headrest and connecting portions respectively located on both sides of the headrest and connected to the headrest. The connecting portions are connected to the corresponding second support member and are slidably engaged. The middle of the headrest is concave.

The second connecting column is connected with a first bolt that abuts against the outer surface of the third connecting column through the first threaded hole. The lower surfaces of the second connecting column, the third connecting column and the connecting seat are all located on the same horizontal plane.

[0012] Beneficial effects: The cooperation between the first connecting column and the connecting groove can guide the sliding of the second support member and also increase the connection between the second support member and the first support member. The outer surfaces of the second connecting column and the third connecting column are in contact, which increases the connection stability between the second support member and the first support member. By providing the threaded hole and the first bolt on the second connecting column, it is also ensured that the second support member can be fixed after sliding.

[0013] As a preferred embodiment of the present invention, the connecting seat includes a base. The end face of the base in contact with the patient's shoulder is C-shaped and elastic.

[0014] Beneficial effects: The end face of the base is C-shaped and elastic, which can abut against the patient's shoulder and can also be slightly clamped with the patient's shoulder, increasing the abutting stability between the base and the patient's shoulder.

[0015] As a preferred embodiment of the present invention, the connecting seat further includes two opposite elastic limiting plates. Both of the limiting plates are connected to the base. The base and the two limiting plates cooperate to form a card slot that penetrates through all three ends and is clamped with the patient's shoulder.

[0016] Beneficial effects: The cooperation between the two limiting plates and the base can form a card slot that penetrates through all three ends, which can be clamped with the patient's shoulder and can increase the connection stability between the base and the patient's shoulder.
