Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an ear surgery incision pulling device. Background Art

[0002] Ear surgery is usually an external auditory canal dilation surgery, which is used to expand the narrow ear canal so that the patient can hear clearly. The treatment method is to remove the attachments, remove the cartilage tissue, and adjust the wound sutures appropriately. Patients with ear appendages often have dysplasia on the same side, so when the cartilage is removed, only part of the protrusion is removed, and the subcutaneous part of the face is retained to avoid aggravating facial deformities. For the appendages that are fused with the tragus in front of the tragus, the ear can be reconstructed after the tragus is removed. During the operation, it needs to be expanded with equipment to facilitate the operation.

[0003] The current traction method is a manual retractor, but this method requires multiple people to collaborate in using the retractor, and the pulling force used by each person is different, resulting in poor traction stability. At the same time, too many people can easily cause the surgical field of view to be blocked, thus causing adverse effects on the operation. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an ear surgery incision pulling device.

[0005] The utility model is achieved in this way:

[0006] An ear surgery incision traction device comprises a fixing mechanism and a traction mechanism, wherein the fixing mechanism comprises a first fixing ring and a second fixing ring, the first fixing ring and the second fixing ring are connected, a fixing sleeve is installed on the top of the first fixing ring, and a plurality of fixing frames can be engaged with the outer side of the fixing sleeve, and the traction mechanism comprises a handle and a pulling block, the handle is connected to the pulling block, the pulling block is oval and flat, and a groove is provided at the bottom of the pulling block, and the handle is engaged with the top of the fixing frame.

[0007] The beneficial effect of adopting the above further scheme is that the medical staff holds the handle, presses the pulling block against the skin near the incision, and then moves the handle outward so that the pulling block pulls the skin apart to expose the incision, and the first fixing ring has been pre-fixed on the surgical sterile towel worn by the patient. At this time, the handle can be snapped into the top of the fixing frame. Since the handle has been fixed, the medical staff does not need to hold the handle subsequently. Therefore, the same traction effect can be achieved with fewer people, thereby avoiding the problem of the surgical field being blocked due to too many people.

[0008] Furthermore, the pulling mechanism is made of 304 stainless steel.

[0009] The beneficial effect of adopting the above further solution is that the pulling mechanism made of 304 stainless steel has high safety performance and corrosion resistance.

[0010] Furthermore, the cross-section of the fixing sleeve is trapezoidal, and both sides of the bottom of the fixing sleeve extend to the outside of the first fixing ring.

[0011] Furthermore, a first stop block is installed on one side of the bottom of the fixing frame, a connecting block is installed on the other side of the bottom of the fixing frame, and a second stop block is installed on one side of the connecting block. The first stop block and the second stop block are respectively pressed against the inner side and the outer side of the bottom of the fixing sleeve.

[0012] Furthermore, a plurality of slots are formed at equal distances on the outer edge of the fixing sleeve, and the connecting block is engaged with the slots.

[0013] Furthermore, a placement groove is provided on the top of the fixing frame, and the placement groove is arranged to be cut obliquely, and the handle can be placed in the placement groove.

[0014] Furthermore, a plurality of card blocks are installed on the top of the placement slot, and the card blocks are engaged with the handle.

[0015] The beneficial effect of adopting the above further scheme is that the handle can be placed in the placement groove. Since the pulling handles are mostly inclined, the inclined placement groove can adapt to the inclined handle. The first stop block is pressed against the bottom of the inner ring of the fixed sleeve, and the second stop block is pressed against the bottom of the outer ring of the fixed sleeve. The connecting block is engaged with the slot, and several blocks are allowed to press the top of the handle. The fixing frame can be fixed on the fixed sleeve and the handle can be fixed in the placement groove.

[0016] Furthermore, a non-slip silicone sleeve is installed on the outer side of the handle.

[0017] The beneficial effect of adopting the above further solution is that the anti-slip silicone sleeve can increase the friction between the handle and the placement groove.

[0018] The beneficial effect of the utility model is: the utility model obtains an ear surgery incision traction device through the above design, the medical staff holds the handle, presses the pulling block against the skin near the incision, and then moves the handle outward so that the pulling block pulls the skin open to expose the incision, and the first fixing ring has been pre-fixed on the surgical sterile towel worn by the patient. At this time, the handle can be snapped into the top of the fixing frame. Because the handle has been fixed, the medical staff does not need to hold the handle subsequently. Therefore, the same traction effect can be achieved with fewer people, thereby avoiding the problem of the surgical field of view being blocked due to too many people.
