Problems solved by technology

However, some patients lose consciousness due to anesthesia and other reasons, and cannot actively open their mouths. Various surgical instruments need to be used to open the patient's mouth
If it is used in surgery, the patient's mouth cannot be fixed in a proper position, which is not conducive to the operation; in addition, the patient's unconscious closing action during the operation may bite the doctor or the patient himself

Embodiment 1

[0020] as attached figure 1 Shown, a kind of medical mouth spreader, it comprises upper support block 1 and lower support block 2, the surface of described upper support block 1 and the bottom surface of lower support block 2 have the arc surface structure that matches with oral cavity, upper support The block and the lower support block are connected by a supporting device.

[0021] as attached figure 1 As shown, the supporting device is composed of two supporting parts on the left and right. The use of two supporting parts is to ensure the stability of the support, and the second is to leave enough space for the operation of the medical staff. The gap can be operated.

[0022] as attached figure 1 As shown, the support portion includes a shaft seat 3 arranged on the surface of the lower support block, a swing rod 4 and a sliding groove 5 horizontally arranged on the upper support block, the top of the swing rod 5 has a wheel shaft 6, and the wheel shaft 6 is fixed with a ...

Embodiment 2

[0031] The oral retractor provided in this embodiment is further improved on the basis of Embodiment 1.

[0032] The sliding grooves of the oral spreader provided in Example 1 are set on the front and rear side surfaces of the upper support block. First, two steps need to be provided on the front and rear side surfaces; 6 through cavity 15 for sliding. As a result, firstly, the processing is complicated, and secondly, the second-level steps provided on the upper support block will cause obstacles to the operation, especially the second-level steps on the rear side of the upper support block will cause discomfort to the patient, and the end of the wheel shaft is located at the second-level The outside of the step surface of the step can sometimes cause damage to the patient's oral cavity. In order to solve this technical problem, this embodiment further improves the arrangement position of the sliding groove.

[0033] as attached Figure 5-7 As shown, in this embodiment, the...

Abstract

The invention relates to the technical field of medical apparatuses and provides a medical oral cavity distracter through aiming at defects and shortcomings in the prior art. The medical oral cavity distracter comprises an upper supporting block and a lower supporting block, the surface of the upper supporting block and the bottom surface of the lower supporting block are of arc-shaped structures, and the upper supporting block is connected to the lower supporting block through a supporting device; the supporting device is composed of a left supporting portion and a right supporting portion, each of the supporting portions comprises a shaft seat arranged on the upper surface of the lower supporting block, a swing rod and a sliding groove horizontally formed in the upper supporting block, the top end of the swing rod is provided with a wheel shaft, a road wheel is fixed on the wheel shaft, the road wheel is located in the sliding groove, and the bottom end of the swing rod is fixedly connected to a supporting shaft on the shaft seat; the medical oral cavity distracter further comprises a driven gear on the supporting shaft and a driving gear which is engaged to the driven gear. The medical oral cavity distracter provided by the invention has the beneficial effects that the medical oral cavity distracter is simple in structure, reasonable in setting, low in manufacturing cost and convenient to operate, can stably maintain opening of the oral cavity of a patient, and smooth treatment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical oral retractor. Background technique [0002] In oral surgery and inspection, in order to facilitate operation, the patient's mouth needs to be opened to a certain extent and kept for a certain period of time. However, some patients lose consciousness due to anesthesia and other reasons, and cannot open their mouths actively, so various surgical instruments need to be used to prop up the patient's oral cavity. If it is used in an operation, it cannot fix the patient's mouth in a proper position, which is not conducive to the operation; in addition, the patient's unconscious closing action during the operation may bite the doctor or the patient himself. [0003] Therefore, it is necessary to carry out further technological innovation to the existing medical oral retractor. Contents of the invention [0004] Aiming at the defects and deficiencies of the pr...
