Technical Field
[0001] This utility model relates to the field of gastroscopy bites, specifically a gastroscopy bite with a guidewire lock. Background Technology
[0002] The endoscope bite is mainly used during gastroscopy to hold the patient's mouth open, allowing the doctor to perform the procedure smoothly. One existing type of endoscope bite is... Figure 1 The device includes an upper baffle 1 with a through hole 11 at its center. Fixing holes 12 for connecting to the two ends of an elastic fixing band are provided on the outer side of the baffle 1 outside the through hole 11. A vertical cylindrical biting part 2 is fixedly provided on the lower side of the baffle 1 below the through hole 11. An annular protrusion 21 is fixedly provided on the outer surface of the lower end of the biting part 2. A tongue-pressing part 22 extends downward from the lower rear end face of the biting part 21. In use, the biting part can be inserted into the patient's mouth. The tongue-pressing part blocks the tongue, the annular protrusion prevents slippage, and the elastic fixing band can be placed behind the patient's head for auxiliary fixation.
[0003] The aforementioned endoscope incision can meet the needs of gastroscopy. However, when inserting a feeding tube into the stomach via the mouth, it is necessary to first insert the endoscope into the stomach, then insert a guidewire through the endoscope's channel, and finally withdraw the endoscope. After the endoscope is withdrawn, the guidewire is prone to displacement (inward or outward). To prevent this displacement, a nurse usually holds the guidewire with gauze to hold it in place. This method is unreliable and not standard practice. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gastroscopy bite with a guidewire lock, comprising an upper baffle, a through hole at the center of the baffle, fixing holes for connecting to the two ends of an elastic fixing band on the outer side of the through hole, a vertical cylindrical biting part fixedly provided on the baffle below the through hole, an annular protrusion fixedly provided on the outer surface of the lower end of the biting part, and a tongue depressor extending downward from the lower end face of the rear side of the biting part, and a locking fastener for cooperating with the guidewire fixedly provided on the baffle to the left of the through hole, the locking fastener comprising a vertical first fixing plate, a second fixing plate with a reduced width provided on the upper side of the first fixing plate, a rectangular first notch embedded downward in the middle part of the upper surface of the second fixing plate, a small diameter guidewire hook provided on the second fixing plate in front of the first notch, and a large diameter guidewire hook provided on the second fixing plate behind the first notch;
[0006] A fixing seat is fixed to the right on the rear right surface of the first fixing plate. The right end of the fixing seat is fixedly connected to the horizontal plate, forming a hook for the guide wire to pass through. A strip-shaped through hole in the front-back direction is provided on the first fixing plate on the rear side of the horizontal plate.
[0007] As a preferred technical solution, the small-diameter guide wire hook includes a rectangular through hole in the left and right direction, the rear side of the rectangular through hole is connected to the bottom of the first notch, and the left side of the rectangular through hole is connected to the bottom of the first triangular prism through hole with the pointed end facing upward.
[0008] As a preferred technical solution, the large-diameter guide wire hook includes a second notch with a rear-opening rectangular shape, and the inner end of the second notch is connected to the bottom of a second triangular prism through hole with the tip pointing upwards.
[0009] As a preferred technical solution, the lower end of the second fixing plate on the upper side of the second notch is inclined inward.
[0010] As a preferred technical solution, the area of the vertical cross-section of the second triangular prism through hole is larger than the area of the vertical cross-section of the first triangular prism through hole.
[0011] As a preferred technical solution, a damping structure that cooperates with the guide wire is fixedly provided on the inner side of the cross plate.
[0012] As a preferred technical solution, the damping structure includes a transverse semi-cylindrical silicone protrusion fixed to the inner side of the cross plate, and the front end face of the silicone protrusion is an inclined surface that facilitates the sliding of the guide wire.
[0013] Compared with the prior art, this utility model provides a gastroscopy bite with a guidewire lock, which has the following advantages:
[0014] 1. This utility model uses a horizontal plate fixedly connected to the right end of the fixing base to form a hook for the guide wire to pass through, as well as small-diameter guide wire hooks and large-diameter guide wire hooks. In use, the guide wire can first be locked in the hook (between the horizontal plate and the first fixing plate), then the small-diameter guide wire can slide down from the first notch to the bottom, then slide forward into the rectangular through hole, and finally be locked upward into the first triangular prism through hole. The large-diameter guide wire can be locked forward from the second notch on the rear side of the second fixing plate, and then be locked upward into the second triangular prism through hole. The whole system locks the guide wire and solves the problem of the guide wire being unreliable and irregular when held by hand with gauze.
[0015] 2. In this utility model, the lower end of the second fixing plate on the upper side of the second notch is inclined inward, which facilitates the downward sliding of the large-diameter guide wire and guides it towards the second notch during use.
[0016] 3. This utility model has a damping structure fixed on the inner side of the horizontal plate to cooperate with the guide wire. The damping structure includes a transverse semi-cylindrical silicone protrusion fixed on the inner side of the horizontal plate. The front end of the silicone protrusion is an inclined surface to facilitate the sliding of the guide wire. When the guide wire passes through the hook, the silicone protrusion contacts the guide wire, increasing the friction and pressing the guide wire towards the strip-shaped through hole on the rear side, which plays an auxiliary role in fixing the guide wire.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] like Figures 1 to 4As shown, a gastroscopy bite with a guidewire lock includes an upper baffle 1. The baffle 1 has a through hole 11 (elliptical) at its center. The baffle 1 outside the through hole 11 has fixing holes 12 for connecting to both ends of an elastic fixation strap 13 (which is worn over the patient's head; the elastic fixation strap 13 can be a non-adjustable or adjustable length strap). A vertically cylindrical (open at both ends) bite-holding part 2 is fixedly provided at the baffle 1 below the through hole 11. An annular protrusion 21 is fixedly provided on the outer surface of the lower end of the bite-holding part 2. The lower end face of the rear side of part 2 also extends downward to provide a pressure tongue part 22. A locking device 3 that cooperates with the guide wire is fixed on the baffle 1 to the left of the through hole 11. The locking device 3 includes a vertical first fixing plate 31. A second fixing plate 32 with a narrower width (narrower from front to back) is provided on the upper side of the first fixing plate 31. A rectangular first notch 33 is embedded downward in the middle part of the upper surface of the second fixing plate 32. A small diameter guide wire hook is provided on the second fixing plate 32 in front of the first notch 33. A large diameter guide wire hook is provided on the second fixing plate 32 behind the first notch 33. A fixing seat 38 is fixed to the right on the right side of the rear side of the first fixing plate 31. The right end of the fixing seat 38 is fixedly connected to the horizontal plate 39, forming a hook (inverted L-shape) for the guide wire to pass through. A strip-shaped through hole 311 in the front-back direction is provided on the first fixing plate 31 behind the horizontal plate 39.
[0026] The small-diameter guide wire hook includes a rectangular through hole 34 in the left and right directions. The rear side of the rectangular through hole 34 is connected to the bottom of the first notch 33, and the left side of the rectangular through hole 34 is connected to the bottom of the first triangular prism through hole 35 with the tip pointing upward.
[0027] The large-diameter guide wire hook includes a second notch 36 with a rear-opening rectangular shape, the inner end of which is connected to the bottom of a second triangular prism through hole 37 with the tip pointing upwards.
[0028] The lower end of the second fixing plate 32 on the upper side of the second notch 36 is inclined inward to form a slope.
[0029] The area of the vertical cross-section of the second triangular prism through hole 37 is larger than the area of the vertical cross-section of the first triangular prism through hole 35. This is to facilitate fixing a guide wire with a larger diameter.
[0030] In use, the guide wire can first be locked in the hook (between the horizontal plate 39 and the first fixing plate 31). Then, the small-diameter guide wire can slide down from the first notch 33 to the bottom, then slide forward into the rectangular through hole 34, and finally be locked upward into the first triangular prism through hole 35. The large-diameter guide wire 4 can be locked forward from the second notch 36 on the rear side of the second fixing plate 32, and then be locked upward into the second triangular prism through hole 37. The whole process realizes the locking (fixing) of the guide wire, ensuring that the guide wire does not shift, and solving the problem of unreliable and non-standard fixation of the guide wire by holding gauze. Example 2
[0031] like Figure 5 As shown, a damping structure that cooperates with the guide wire is fixed on the inner side of the horizontal plate 39.
[0032] The damping structure includes a transverse semi-cylindrical silicone protrusion 5 fixed to the inner side of the horizontal plate 39. The front end face of the silicone protrusion 5 is an inclined surface 51 that facilitates the sliding of the guide wire.
[0033] When in use, when the guide wire is inserted into the hook, the silicone protrusion 5 contacts the guide wire, increasing the friction and simultaneously squeezing the guide wire towards the rear strip-shaped through hole 311, which helps to fix the guide wire.
