Description

Technical Field

[0001] The invention relates to the field of lip compression hemostasis, in particular to a lip compressor. Background Art

[0002] Mucocele grows on the mucosa. For excision surgery, the main thing is to fix and stretch the mucosa in the surgical area to play a role in compression and hemostasis, and to press the blood vessels in the surgical area to prevent bleeding. This is to ensure a clear field of vision in the surgical area. Currently, it is done by manual clamping and stretching, which is rather laborious and prone to shaking. Therefore, how to better stretch and fix the mucosa to facilitate surgery is an urgent problem that technicians in this field need to solve. Summary of the invention

[0003] The object of the present invention is to provide a lip compressor to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: a lip compressor, comprising an elastic expansion ring with a "C"-shaped opening, the opening is mainly used for surgical operations, the cross-section of the expansion ring is an arc-shaped ring that fits the lips, and arc-shaped outer splints that can clamp the lips are installed on both sides of the opening of the expansion ring to achieve hemostasis, and also includes a protruding mechanism arranged on the outer splint to facilitate the flipping of the outer splint. The protruding mechanism is mainly to facilitate the application of force, drive the splint to flip and clamp the lips, and then operate from the opening of the expansion ring.

[0005] Preferably, the protrusion mechanism is a convex plate arranged at the upper end of the outer clamping plate close to the center direction of the opening ring, and the end of the convex plate is inclined upward toward the opening ring. The convex plate can be used to apply force to the outer clamping plate.

[0006] Preferably, the outer splint and the expansion ring are integrally formed and are both made of elastic hard plastic. When the convex plate is pushed toward the center of the expansion ring, the outer splint can be opened to clamp the lip to stop bleeding. When the convex plate is pressed downward toward the center of the expansion ring, the outer splint can be opened and the lip can be clamped.

[0007] Preferably, the expansion ring is equipped with an elastic telescopic mechanism in radial direction, which can be telescopic and has elasticity, and the inner end of the telescopic mechanism is equipped with an arc-shaped inner clamping plate for clamping the inner side of the lip from the inside. The inner end refers to the side close to the outer clamping plate, and the inner clamping plate is located between the expansion ring and the outer clamping plate, clamping the lip from the inside. It also includes a pushing mechanism arranged on the expansion ring to drive the convex plate to flip, and the outer clamping plate is driven to flip and clamp the lip by pushing the convex plate to stop bleeding. As the expansion ring expands outward, the clamping force of the outer clamping plate increases, and the hemostatic effect increases.

[0008] Preferably, the telescopic mechanism includes a guide column with a square cross-section fixed to the inner end of the clamping plate, and the guide column passes through the expansion ring in the radial direction. The expansion ring is provided with a guide hole corresponding to the guide column, and the guide hole guides the guide column and has a guiding depth. A spring is provided between the inner clamping plate and the expansion ring and is sleeved on the guide column, and the spring plays a resetting role.

[0009] Preferably, a guide ring fixed on the expansion ring is sleeved on the guide column to increase the guide length and provide greater stability.

[0010] Preferably, the pushing mechanism includes a pushing block fixed on the expansion ring, and the end of the convex plate is inclined upward, the end of the pushing plate is against the lower wall of the convex plate, and when the pushing plate squeezes the convex plate, it can drive the outer clamping plate to clamp the lip of the expansion ring to expand outward, and a relative displacement is generated between the inner clamping plate, which is equivalent to the expansion ring moving outward relative to the inner clamping plate, and then the pushing plate pushes the convex plate outward and upward from the lower side, thereby driving the outer clamping plate to flip, clamp the lip, and increase the clamping force. As the expansion ring expands outward, the expansion force of the inner clamping plate also increases. In this way, the inner and outer clamping plates increase the clamping force at the same time, ensuring the hemostatic effect and achieving hemostatic adjustment.

[0011] Preferably, an elastic component is also included between the push plate and the convex plate to prevent shaking, thereby preventing the push plate from shaking.

[0012] Preferably, the elastic component is a rubber strip arranged between the push plate and the convex plate. When the push plate pushes the convex plate outward, the rubber strip contracts and the two are pressed against each other without shaking. When the push plate is retracted to the middle of the expansion ring, the convex plate is pulled against the upper end of the push plate by the rubber strip, and elastically pressed tightly to avoid shaking.

[0013] Preferably, threaded columns with opposite thread rotation directions are fixed to the inner cavity wall of the expansion ring, and the two threaded columns are connected by a bidirectional threaded cylinder. The bidirectional threaded cylinder is rotated to drive the two threaded columns to move closer or farther synchronously to achieve expansion or recovery.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The expansion ring expands the lips and mucosa, while the external splint clamps the mucosa and blood vessels to achieve hemostasis. The opening of the expansion ring is conducive to operation and exposes the field of vision;

[0016] 2. The expansion ring expands outward to expose a wider field of view. At the same time, the expansion area of ​​the expansion ring can be changed by rotating the bidirectional threaded cylinder. As it expands outward, the push plate pushes the convex plate, and the outer clamping plate flips to clamp the lip for fixation and hemostasis. The greater the expansion distance, the greater the clamping force and the better the hemostasis effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 2

[0030] See also Figures 3 to 7 The present invention provides a technical solution for a lip compressor: a lip compressor, comprising an elastic expansion ring 1 with a "C"-shaped opening, the opening is mainly used for surgical operations, the cross-section of the expansion ring 1 is an arc-shaped ring that fits the lips, and arc-shaped outer splints 2 that can clamp the lips are installed on both sides of the opening of the expansion ring 1 to achieve hemostasis, and also includes a protruding mechanism arranged on the outer splint 2 to facilitate the flipping of the outer splint 2. The protruding mechanism is mainly to facilitate the application of force, drive the splint 2 to flip and clamp the lips, and at the same time, clamp the blood vessels without bleeding, and then operate from the opening of the expansion ring 1.

[0031] Correspondingly, threaded columns 10 with opposite thread directions are fixed on the inner cavity wall of the expansion ring 1, and the two threaded columns 10 are connected by a bidirectional threaded barrel 11. Rotating the bidirectional threaded barrel 11 drives the two threaded columns 10 to move closer or farther synchronously to achieve expansion or recovery.

[0032] The raised mechanism is a raised plate 3 arranged at the upper end of the outer splint 2 near the center direction of the expansion ring 1, and the end of the raised plate 3 is inclined upward toward the expansion ring 1. The outer splint 2 can be exerted with force through the raised plate 3. The expansion ring 1 is provided with an elastic telescopic mechanism in the radial direction, which can be extended and retracted and has elasticity, and the inner end of the telescopic mechanism is provided with an arc-shaped inner splint 4 that clamps the inner side of the lip from the inside. This inner end refers to the side close to the outer splint 2, and the inner splint 4 is located between the expansion ring 1 and the outer splint 2, clamping the lip from the inside, and also includes a pushing mechanism arranged on the expansion ring 1 to drive the raised plate 3 to flip, and the outer splint 2 is driven to flip and clamp the lip by pushing the raised plate 3 to stop bleeding.

[0036] Working principle: the expansion ring 1 expands the lip and mucosa, while the outer splint 2 clamps the mucosa and blood vessels to achieve hemostasis. The opening of the expansion ring 1 is conducive to operation and exposes the field of vision. The expansion ring 1 expands outward to expose a larger field of vision. At the same time, by rotating the bidirectional threaded cylinder 11, the expansion area of ​​the expansion ring 1 can be changed. As it expands outward, the push plate 8 pushes the convex plate 3, and the outer splint 2 flips to clamp the lip for fixation and hemostasis. The larger the expansion distance, the greater the clamping force, and the better the hemostasis effect.
