Description

Technical Field

[0001] This utility model relates to the field of hemostatic instruments, specifically a vertical electric hemostatic instrument. Background Technology

[0002] A hemostat is a medical device primarily used to control bleeding during surgery. It blocks blood flow through physical pressure or energy coagulation mechanisms, providing a clear surgical field and reducing blood loss. Hemostats achieve precise blood control through physical or energy mechanisms, making them a key tool for improving surgical efficiency.

[0003] Furthermore, the vertical electric hemostat is a medical device that uses air pressure to compress blood vessels in the limbs to block blood flow. It is mainly used to reduce bleeding during orthopedic, surgical, and other limb surgeries.

[0004] Traditional vertical electric hemostats typically consist of a base at the bottom and a main unit at the top. The main unit and the base are usually fixed in place (fixed angle), making it difficult to adjust the angle of the main unit. When medical staff are tall (short) or the equipment is close (far) from them, the viewing angle and reflection issues can make it difficult for them to see the readings on the main unit.

[0005] A search revealed that patent application number CN201821939146.2 discloses an electric pneumatic hemostat, including a support base, a hemostat body and a tourniquet mounted on the support base. The hemostat body houses a controller and an air pump, which are signal-connected to the controller. A first three-way valve is installed on a first air guide pipe connected to the air pump's outlet. An air inlet valve is installed on the first air guide pipe between the air pump and the first three-way valve. Two other connectors of the first three-way valve are connected to an interface and a second three-way valve, respectively. The interface is fixedly mounted on the hemostat body. A second air guide pipe is installed on the tourniquet, with its other end connected to the interface. Two other connectors of the second three-way valve are equipped with a fast-release solenoid valve and a slow-release solenoid valve, respectively. The air inlet valve, fast-release solenoid valve, and slow-release solenoid valve are all signal-connected to the controller. This utility model aims to improve upon the limited release function options of existing electric pneumatic hemostats, making the functions of the electric pneumatic hemostat more aligned with actual needs.

[0006] The hemostat in the above-mentioned scheme is fixedly mounted on a support base, which has the problem of reflection caused by different viewing angles, making it difficult to see the values. Therefore, we need to propose a vertical electric hemostat. Utility Model Content

[0007] The purpose of this utility model is to provide a vertical electric hemostat. Through the design of the connecting column, the angle of the hemostat main unit can be adjusted horizontally. Through the design of the adjustment mechanism, the angle of the hemostat main unit can be adjusted vertically by simply turning the handwheel, with the cooperation of gears and worm gears. After adjustment, the angle can be automatically locked. This solves the problem that medical staff cannot see the values ​​on the display screen of the hemostat main unit due to reflection problems in different application scenarios, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vertical electric hemostat, comprising a base, a storage frame installed on the outer wall of the base, and a hemostat main unit rotatably installed on the top of the base. A connecting column is rotatably installed on the top of the base, and an adjustment mechanism for driving the hemostat main unit to rotate vertically is installed on the top of the connecting column.

[0009] The adjustment mechanism includes a mounting frame, a rotating shaft is rotatably mounted inside the mounting frame, a fixing block is sleeved on the outer wall of the rotating shaft, and the hemostatic instrument main unit is mounted on the fixing block.

[0010] Preferably, the top of the base has a groove, a damping bearing is installed inside the groove, and the bottom of the connecting column is inserted into the inner ring of the damping bearing.

[0011] Preferably, both sides of the mounting bracket are equipped with stop bars to limit the rotation angle of the hemostat main unit to -40° to 40°.

[0012] Preferably, the mounting bracket also has a rotatable worm gear and a rotating shaft installed inside, and one end of the worm gear passes through the mounting bracket and is connected to a handwheel.

[0013] Preferably, a turbine is sleeved on the outer wall of the second rotating shaft, and the turbine meshes with the worm gear.

[0014] Preferably, a second gear is also sleeved on the outer wall of the second rotating shaft, and a first gear is sleeved on the outer wall of the worm gear. The first gear meshes with the second gear, and the diameter of the first gear is smaller than the diameter of the second gear.

[0015] Preferably, a sleeve is fixedly fitted onto the outer wall of the base, and the storage frame is installed on the outer wall of the sleeve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model achieves horizontal angle adjustment of the hemostat main unit through the design of the connecting column. Through the design of the adjustment mechanism, the angle of the hemostat main unit can be adjusted vertically by simply turning the handwheel, with the cooperation of gears and worm gears.

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a vertical electric hemostat, including a base 1, a storage frame 2 installed on the outer wall of the base, and a hemostat main unit 3 rotatably installed on the top of the base 1. A connecting column 5 is rotatably installed on the top of the base 1, and an adjustment mechanism 4 for driving the hemostat main unit 3 to rotate vertically is installed on the top of the connecting column 5.

[0024] The base 1 includes a support seat with pulleys, a column connected to the support seat, and a storage frame 2 installed on the column.

[0025] By setting the connecting column 5, the horizontal angle of the hemostat host 3 can be adjusted, so that the display screen on the hemostat host 3 can face the medical staff without moving the entire hemostat device. By designing the adjustment mechanism 4, the vertical angle of the hemostat host 3 can be adjusted, which can be used by medical staff of different heights and at different distances from the hemostat host 3 to the medical staff, reducing or even eliminating the problem of not being able to see the values ​​on the display screen of the hemostat host 3 due to reflection.

[0026] The adjustment mechanism 4 includes a mounting frame 41, which is U-shaped. A rotating shaft 43 is rotatably mounted inside the mounting frame 41, and a fixing block 44 is sleeved on the outer wall of the rotating shaft 43. The hemostat main unit 3 is mounted on the fixing block 44. By rotating the rotating shaft 43, the fixing block 44 is driven to rotate, thereby realizing the vertical angle adjustment of the hemostat main unit 3.

[0027] The top of the base 1 has a groove 11, and a damping bearing 6 is installed inside the groove 11. The bottom of the connecting column 5 is inserted into the inner ring of the damping bearing 6. Due to the design of the damping bearing 6, after the hemostat main unit 3 is rotated laterally, the hemostat main unit 3 will only rotate laterally when a large traction force is applied to the hemostat main unit 3, thus preventing angular deflection caused by accidental contact with the hemostat main unit 3.

[0028] Both sides of the mounting bracket 41 are equipped with stop bars 42 to limit the rotation angle of the hemostat main unit 3 to -40° to 40°, so as to prevent the vertical angle adjustment of the hemostat main unit 3 from being too large.

[0029] The mounting bracket 41 also houses a rotatable worm gear 46 and a rotating shaft 47. One end of the worm gear 46 passes through the mounting bracket 41 and is connected to a handwheel 45.

[0030] A turbine 48 is sleeved on the outer wall of the rotating shaft 47. The turbine 48 meshes with the worm gear 46. The meshing of the turbine 48 and the worm gear 46 enables the self-locking function after vertical angle adjustment.

[0031] Gear 2 410 is also sleeved on the outer wall of the rotating shaft 2 47, and gear 1 49 is sleeved on the outer wall of the worm gear 46. Gear 1 49 meshes with gear 2 410. The diameter of gear 1 49 is smaller than the diameter of gear 2 410, which facilitates the control of the vertical angle adjustment accuracy of the hemostat host 3.

[0032] Turning the handwheel 45 causes the worm gear 46 to rotate. With the cooperation of the worm gear 46 and the turbine 48, the rotating shaft 47 rotates, which in turn drives the gear 49 to rotate. With the meshing of the gear 49 and the gear 410, the rotating shaft 43 and the fixed block 44 rotate, thereby driving the hemostat main unit 3 to achieve vertical angle adjustment.

[0033] A sleeve is fixedly fitted on the outer wall of the base 1, and a storage frame 2 is installed on the outer wall of the sleeve. The storage frame 2 is used to store tourniquets.

[0034] When in use, push the device into the operating room and put the tourniquet on the patient's wrist. The pressure of the tourniquet can be observed in real time through the hemostat host 3. For different application scenarios (medical staff of different heights, distance between the hemostat host 3 and the medical staff), the angle of the hemostat host 3 needs to be adjusted to adapt to the medical staff's perspective and reduce the impact of unclear readings caused by reflection.

[0035] Specifically, first, rotate the connecting column 5 to adjust the hemostat host 3 so that it faces the medical staff. Then, according to the actual situation, adjust the vertical angle of the hemostat host 3. Rotate the handwheel 45 to drive the worm gear 46 to rotate. With the cooperation of the worm gear 46 and the turbine 48, the rotating shaft 47 rotates, which in turn drives the gear 49 to rotate. With the meshing of the gear 49 and the gear 410, the rotating shaft 43 and the fixing block 44 rotate, thereby driving the hemostat host 3 to achieve vertical angle adjustment.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
