Embodiment 1

[0048] Figure 1~3 Respectively, a structural representation of a minimally invasive scalp retractor in an embodiment of the present application Figure 1 , structural representation Figure II and a front view, such as Figure 1~3 As shown, the retractor includes a base 10 , a plectrum 20 and an adjustment part 40 .

[0049] The first end of the dial 20 is arranged on the base 10 so as to reciprocate along the first direction, and the second end of the dial 20 is rotatably and lockably connected with a dial 30 so that it can be adjusted The inclination direction of the dial 30 on the dial 20; the adjustment part 40 is connected with the dial 20 to drive the dial 20 to move on the base 10, thereby adjusting the dial 20 the position in the first direction.

[0050] When using the retractor, the patient lies flat so that the plectrum 20 is located on one side of the patient's head, then the first direction is the up-down direction, that is, the vertical direction, and the se...

Embodiment 2

[0066] The difference between this embodiment and Embodiment 1 is that: the connection method between the sleeve 51 and the rotating shaft 61 is different. In this embodiment, the sleeve 51 and the rotating shaft 61 are connected by threads, as follows:

[0067] Such as Figure 6 , 7 As shown, the sleeve 51 is provided with an internal thread 53, the rotating shaft 61 is provided with an external thread 63, and the external thread 63 is engaged with the internal thread 53, and the external thread section on the rotating shaft 61 (set The length of the part of the external thread) is longer than the length of the internal thread section (the part where the internal thread is provided) on the sleeve 51, so that the sleeve 51 and the shaft 61 pass through the internal thread 53 and the After the external thread 63 is screwed and fitted, the rotating shaft 61 can still rotate with the sleeve 51, similar to the jack, so as to realize the stepless adjustment of the inclination angl...

Embodiment 3

[0070] The difference between this embodiment and Embodiment 1 is that the locking method of the sleeve 51 and the rotating shaft 61 is different. In this embodiment, the sleeve 51 and the rotating shaft 61 are locked by the second screw 70, specifically as follows:

[0071] The rotating shaft 61 is rotatably arranged in the sleeve 51, and the sleeve 51 is provided with a radial hole, and the inner end of the second screw 70 passes through the radial hole and abuts against the rotating shaft. 61 to lock the rotating shaft 61 in the sleeve 51, so as to realize the stepless adjustment of the inclination angle of the plectrum 20, and any angle can be adjusted, which is more practical.

Abstract

The invention discloses a minimally invasive scalp retractor. The minimally invasive scalp retractor comprises a base, a shifting piece and an adjusting part, wherein the shifting piece is arranged on the base in the mode that the shifting piece can move in a reciprocating mode in the first direction, and a shifting head is connected to the shifting piece in a rotatable and lockable mode; and the adjusting part is connected with the shifting piece so as to drive the shifting piece to move on the base, and therefore the position of the shifting piece in the first direction is adjusted. According to the embodiment of the invention, the technical problem that in the prior art, a device for lifting scalp in the minimally invasive temporomuscular valve cutting process is lacked is effectively solved, the blank is filled, and minimally invasive temporomuscular valve cutting under an endoscope is realized. The minimally invasive scalp retractor has the beneficial effects that the operation is convenient, the surgery efficiency is improved, the bleeding amount is reduced, the infection incidence rate is reduced, the postoperative scar is reduced, the trauma to a patient is relieved, and the application range of the temporal muscle flap is widened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a minimally invasive scalp retractor. Background technique [0002] Temporal muscle flap is a common repair material for repairing defects after resection of skull base and nasosinus tumors. An important step in the repair of postoperative defects with the temporalis muscle flap is the removal of the temporalis muscle flap. The traditional method of excision of the temporal muscle flap is to make an arc-shaped incision along the attachment of the temporal muscle on the top of the head, cut the scalp, separate and free the temporal muscle, transfer the temporal muscle to the site to be repaired, and finally suture the scalp incision. The above-mentioned surgical procedure is mature, but the obvious disadvantages are large scalp incision, heavy bleeding, obvious trauma to the patient, high incidence of postoperative infection, and obvious scar. It is not suitable for p...
