Technical Field

The utility model relates to the field of medical equipment, especially, relate to retractor in midair under chamber mirror.

Background

Surgical operations involve the introduction of an external device into the body to perform resection, suturing, or drainage, among others. In current surgical procedures, a reduction in the wound area is generally sought, but at the same time, the active area of the surgical instrument is correspondingly reduced, on the basis of which the instruments used for traction are made more difficult to use. However, in the operation, some soft tissues such as fascia and important organs often have the effect of hindering the operation, so a device which can pull the soft tissues but does not occupy or occupies little operation space is needed to pull the soft tissues.

Preferably, the fixing clamp 1 can be a pug, the top of the fixing clamp is provided with a nondestructive gullet, and the tail of the fixing clamp is provided with a fixing ring structure 11.

Preferably, the middle part of the traction needle 2 is provided with a thread eye structure 21, and the connecting thread 3 is fixed with the traction needle 2 through the thread eye structure 21.

Preferably, 1 or more elastic threads are used as the connecting thread 3.

Preferably, the fixing ring 4 comprises a fixing frame 41 and a needle frame 42, the fixing frame 41 is fixedly connected with the patient through a film, the needle frame 42 is in limited connection with the fixing frame 41 through a ratchet structure, and a traction needle placing area is arranged on the needle frame 42.

Preferably, the ratchet structure comprises a ratchet ring 43 and a limiting block 44, and the limiting block 44 is in limiting connection with the ratchet ring 43 through an elastic sheet 45.

Preferably, the needle holder 42 is formed with a through hole structure having a diameter larger than the radius of the traction needle 2.

Preferably, the fixing clamp 1 is further provided with a long-handled clamp, and the front section of the long-handled clamp is provided with a guide structure meshed with the tail end of the fixing clamp 1.

The utility model has the advantages that:

1. the soft tissue of the surgical site can be pulled from outside the patient;

2. does not occupy the operation area, and is convenient for the internal observation and the instrument operation of the patient of the medical staff.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1-5, the present invention comprises: fixation clamp 1, draw needle 2 and solid fixed ring 4, fixation clamp 1 and draw needle 2 and connect through connecting wire 3, gu fixed ring 4 fixes outside the patient to carry on spacingly to connecting wire 3.

After the two ends of the connecting line 3 are respectively fixed with the fixing clamp 1 and the traction needle 2, the fixing frame 1 is sent into the body of a patient and fixed on a part which is required to be pulled, then the traction needle 2 is driven to be reversely pricked out of the body of the patient, and the traction needle is fixed by the fixing ring 4 and pulled, thereby lifting the traction part of the fixing end. At the end of the operation, the fixation clamp 1 can be completely removed by cutting the external connecting wire 3 and then removing it.

Fixation clamp 1 can adopt the pug, and the not damaged tooth's socket has been seted up at the top, and solid fixed ring structure 11 has been seted up to the afterbody, under the less prerequisite of guaranteeing fixation clamp 1 volume, reduces the injury to holding the position with, and solid fixed ring structure 11 is used for connecting wire 3.

The middle part of the traction needle 2 is provided with a thread eye structure 21, and the connecting wire 3 is fixed with the traction needle 2 through the thread eye structure 21, so that the fixing ring 4 can be embedded and fixed conveniently.

Connecting wire 3 adopts 1 or many elastic wires, when guaranteeing traction force, prevents connecting wire 3 overload fracture, perhaps plastic deformation.

The fixing ring 4 comprises a fixing frame 41 and a needle frame 42, the fixing frame 41 is fixedly connected with a patient through a film, the needle frame 42 is in limited connection with the fixing frame 41 through a ratchet structure, a traction needle placing area is arranged on the needle frame 42, the traction needle 2 is fixed in a limited mode through the traction needle placing area, the needle frame 42 is driven to rotate after the ratchet structure is screwed, a connecting wire 3 is wound, and therefore the lifting action is completed.

The ratchet structure comprises a ratchet ring 43 and a limiting block 44, wherein the limiting block 44 is in limiting connection with the ratchet ring 43 through an elastic sheet 45, and the ratchet ring 43 is sequentially prevented from rotating, so that the connecting wire 3 is released.

The needle frame 42 is provided with a through hole structure, and the diameter of the through hole structure is larger than the radius of the traction needle 2, so that the traction needle 2 can pass through and be limited subsequently.

Fixation clamp 1 still is supporting to have long-handled pincers, and the anterior segment of long-handled pincers is equipped with the guide structure who meshes mutually with the tail end of fixation clamp 1, and when fixation clamp 1 sent into the patient internal, unable with handheld mode send into, need accomplish through long-handled pincers, in order to prevent the landing also be convenient for get the centre gripping when unloading simultaneously, need the guide structure mesh and increase friction. Preferably, the front section of the long-handle pliers is an arc-shaped bulge, and the tail end of the fixing clamp 1 is an arc-shaped recess.
