Problems solved by technology

[0003] When performing laparoscopic thyroid surgery, due to the small space, it will increase the difficulty of the operation. It is often necessary to suspend the neck skin to increase the operating space of the surgical site. Pulling, because the suture pulling method needs to suture the skin on the neck, it is an invasive method, and the pulling is point-like pulling, that is, the suture can be pulled, and the skin at other parts of the suture point will be sunken, resulting in During the operation, the stretching is uneven, and after the operation, there will be bleeding, congestion, edema, etc. at the skin sutures in the neck, which brings confusion to the doctor and the patient. It is a paste method, which is very inconvenient to install and disassemble, and is prone to angular deviation when pulling

Embodiment 1

[0051] like Figure 1-Figure 7 As shown, a laparoscopic thyroid skin pulling device includes a lifting mechanism 1, a pulling mechanism 2, an adsorption mechanism 3, and a connecting mechanism 4. Eight pulling mechanisms 2 are connected to the outer side of the lifting mechanism 1 through the connecting mechanism 4. The pulling mechanism 2 The lower end is connected to the adsorption mechanism 3, and the hoisting mechanism 1 and the traction mechanism 2 are both equipped with a wire-releasing mechanism 5;

[0052] The hoisting mechanism 1 includes a center base 11, a suspension wire 12, and a universal swivel hook 13. The center base 11 is provided with a pay-off mechanism 5, the pay-off mechanism 5 is connected with a suspension wire 12, and the upper end of the suspension wire 12 is equipped with a universal swivel hook 13;

[0053] The traction mechanism 2 includes a traction rope 21, an axial positioning shaft 22, an axial locking bolt 23, and a longitudinal positioning co...

Embodiment 2

[0058] like Figure 8 , the difference between this embodiment and embodiment 1 is:

[0059] The connection mechanism 4 includes a connection block 41, a connection groove 42, a tapered block 411, and a tapered groove 412. The connection block 41 is connected to one end of the traction connection seat 25, and a connection groove 42 is provided between the connection block 41 and the center seat 11. The connecting block 41 is provided with a tapered block 411, and a tapered slot 412 is provided between the tapered block 411 and the center base 11. When the traction connecting seat 25 needs to be installed, the connecting block 41 is inserted into the inner side of the connecting groove 42. , the conical clamping block 411 is stuck inside the conical clamping slot 412, and can be clamped quickly. When it needs to be removed, just pull the conical clamping block 411 to take it out; the conical clamping block 411 and the connecting block 41 are integrally formed, The tapered clam...

Abstract

The invention discloses a laparoscopic thyroid gland skin traction device which comprises a hoisting mechanism, traction mechanisms, adsorption mechanisms and connecting mechanisms, the outer side of the hoisting mechanism is connected with the eight traction mechanisms through the connecting mechanisms, and the lower ends of the traction mechanisms are connected with the adsorption mechanisms; and pay-off mechanisms are arranged in the hoisting mechanism and the traction mechanisms. The traction surface of the device is improved through the hoisting mechanism and the eight traction mechanisms, the device adapts to various traction modes, the included angle between suction cup and traction rope is conveniently adjusted through cooperation of the traction mechanisms and the adsorption mechanisms, and therefore it is guaranteed that the suction cups drive the skin to be horizontally pulled during traction.

Description

technical field [0001] The invention relates to the field of laparoscopic surgery, in particular to a laparoscopic thyroid skin pulling device. Background technique [0002] With the development of modern medicine, minimally invasive surgery has become the development direction of today's surgical operations. Minimally invasive surgery has the advantages of less trauma, faster recovery, and less pain, and has become the common goal and direction of modern medicine. Laparoscopic techniques are gradually replacing traditional surgery in some respects. Laparoscopic thyroid surgery is a highly recommended cosmetic surgery in recent years, that is, a puncture incision is made on the bilateral nipples or under the lips, and this incision has the effect of hiding the surgical wound. Puncture the cannula to create space for thyroidectomy. On the basis of the operation method required by the thyroid gland, the neck will not increase surgical scars, and the scars will be hidden on th...
