Embodiment 1

[0024] Such as figure 1 , shown in Fig. 2, muscle separator of the present invention is made up of handle 1, swivel 2, fixed rod 3, moving rod 4, connecting rod 5, swing rod 6 etc.

[0025] The fixed rod 3 is cylindrical, and the head end of the fixed rod 3 is made of stainless steel; the fixed rod tail end 32 is made of alloy steel or hard plastic, and the outer wall is threaded, and there are two longitudinal openings 33 on the rod wall, such as Figure 5 shown. The head end and the tail end 32 of the fixing rod 3 are fixedly connected into one body through a plastic ring 31 , and the axis centers of the two ends coincide.

[0026] The fixed rod 3 is set outside the moving rod 4; the head end of the moving rod 4 is hinged to the swing rod 6 through the connecting rod 5 and two hinge pins 7a, 7b, and the swing rod 6 is connected to the fixed rod 3 through another hinge pin 7c at the same time. hinged. There is a symmetrical boss 41 at the rear end of the moving rod 4, whic...

Embodiment 2

[0032] As shown in Figure 6, in this embodiment, there is a longitudinal bump 61 in the middle of the tail end of the swing rod 6, and a through groove 63 is arranged on the bump 61; The protrusion 61 at the end is embedded in the groove 43 , and the hinge pin 7 d fixed in the groove 43 transversely passes through the through groove 63 on the swing rod 6 . As shown in FIG. 7 , when the moving rod 4 moves longitudinally relative to the fixed rod 3 , it drives the swing rod 6 to swing around the hinge pin 7 c on the fixed rod 3 . All the other are the same as embodiment one.

[0033] The muscle separator of the present invention cleverly realizes the remote control of the swinging rod, thereby separating the sternocleidomastoid muscle or the subhyoid muscle without damage and bleeding, and avoiding unnecessary bleeding and damage during the operation.

Abstract

This invention discloses a muscle segregator for scope thyroid operation, which is made by binding handle, swivel, fixed rod, movable rod and oscillating rod. The fixed rod is cylindrical-style and the handle is fixed connected with its trail, and the movable rod thrill through the fixed rod and is limited to move at radial the longitudinal direction of the fixed rod; the head end of the oscillating rod is a blunt point, and the trail end of the oscillating rod hinges with the head end of the fixed rod; the head end of the movable rod mobile links with the oscillating rod, and there is screw thread on the trail end of the movable rod; the swivel is in the front of the handle, and its female thread is matched with the screw thread on the trail end of the movable rod. In scope operation, this muscle segregator can unfold thyroid by poking sub-hyoid muscle instead of cutting off it. It solves the problem of unclear operation field and slow resume after operation because of bleeding and damage.

Description

technical field [0001] The invention relates to a medical instrument, especially a muscle separator specially used for laparoscopic thyroid surgery. Background technique [0002] Thyroid disease is a common and frequently-occurring disease, especially in young women. Surgical treatment is one of the ultimate cures for this disease, and it is also the most commonly used and most effective method. Traditional open surgery needs to leave a surgical scar about 6-8cm long on the neck, which leaves a heavy psychological shadow on the patients and seriously affects their daily life, study and work. Laparoscopic thyroid surgery has completely changed this situation. While curing the disease, it can conceal tiny wounds and take into account the advantages of safe resection of thyroid lesions and beauty. It is being carried out more and more widely. [0003] In laparoscopic thyroid surgery, the separation and exposure of the thyroid gland is the key operation. The successful strippin...
