[0036] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the accompanying drawings. Depending on the different accompanying drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0037] Embodiment 1

[0038] As Figure 1 、 2 shown, this embodiment provides a surgical pusher, including: a frame body; a pushing member 3 movably arranged on the frame body; a pushing head 6 arranged at the end of the pushing member 3 and moving synchronously with the pushing member 3, the pushing head 6 being used to contact the patient; a clamp arranged on the frame body to avoid the pushing member 3, the clamp being used to connect the device to be installed.

[0039] Specifically, the frame acts as a frame during use and is used to connect various components in the ejector. The ejector member 3 is movably provided on the frame. Here, the connection method between the ejector member 3 and the frame is not specifically limited, as long as the effect that the ejector member 3 can be movably installed on the frame can be achieved. The connection methods between the ejector member 3 and the frame include but are not limited to screw connection, sliding contact, etc., which are installation methods that can achieve movable connection. The ejector head 6 is provided at the end of the ejector member 3 for contacting the patient's skin. Preferably, the material of the ejector head 6 is medical-grade silica gel to ensure its softness and non-toxicity and avoid harm to the patient's skin. The physician controls the movement of the ejector member 3 to control the ejector head 6 to push against the patient's skin, and the ejector head 6 pushes against the patient's skin to achieve the desired effect of the physician. For example, by pushing against the perineum skin with the ejector head 6, the stump of the posterior urethra protrudes from the bottom of the pelvis towards the abdominal cavity. After the posterior urethra is fully exposed, it is beneficial for the anastomosis between the bladder neck and the posterior urethra. The fixture is used to connect the frame to the device to be installed, so that the physician can concentrate on controlling the ejector head 6 without fixing the frame 2. The fixture is fixed to the device to be installed by clamping. Compared with connection by fasteners, the operation of connecting by the fixture is more convenient, and it can be adjusted in real time during the operation. The device to be installed is preferably the operating table 1. Of course, the device to be installed can also be other devices that can carry the patient, as long as the function of carrying the patient can be achieved. Preferably, the operating table 1 includes a main bed body and two sub-bed bodies connected to one side of the operating table 1. A certain angle is formed between the two sub-bed bodies, and the frame is fixed between the two sub-bed bodies by the fixture. In the ejector of this embodiment, by setting the fixture to fix the frame to the device to be installed, the physician can concentrate on operating the ejector member 3 during the surgical operation, with high efficiency, and the frame is fixed by the fixture, so its stability is also high.

[0040] Furthermore, the frame includes: a sleeve 42, which is sleeved outside the ejector member 3 and is screwed to the ejector member 3; a base 41, and the sleeve 42 is arranged on the base 41. The sleeve 42 is arranged on the base 41, and the rotation of the sleeve 42 is restricted by the base 41 to prevent the sleeve 42 from rotating together with the ejector member 3. During the surgical operation, the physician can rotate the ejector member 3 to make the ejector member 3 reciprocate relative to the sleeve 42, and the thread has a self-locking property. After the physician moves the ejector member 3 to the preset position, self-locking can be achieved through the thread, ensuring that the ejector member 3 can still remain in the preset position without moving after the physician releases the ejector member 3.

[0041] Such as Figure 5As shown in the figure, further, the frame body further includes: a rotating shaft 421, the rotating shaft 421 is arranged on the sleeve 42, and the rotating shaft 421 at least partially extends into the machine base 41; a locking channel, the locking channel is arranged on the machine base 41 and at least partially contacts the rotating shaft 421; a locking member 411, the locking member 411 is screwed into the locking channel, and the axial length of the locking member 411 is greater than the axial length of the locking channel. The setting of the rotating shaft 421 can effectively prevent the sleeve 42 from rotating. During the operation, the setting of the rotating shaft 421 is also beneficial for the doctor to adjust the angle of the pushing member 3, so that the pushing head 6 can push against the preset part of the patient during the movement. After adjusting the angle of the pushing member 3, by rotating the locking member 411, it makes a feeding movement in the locking channel. After moving a certain distance, it contacts the rotating shaft 421, and locks the rotating shaft 421 through the friction force between the two, and fixes the pushing member 3 to the preset angle.

[0042] Further, a plurality of locking grooves are arranged at intervals along the circumferential direction of the rotating shaft 421, and the locking grooves are adapted to the end of the locking member 411. During the movement of the locking member 411 and contacting the rotating shaft 421, by extending the end of the locking member 411 facing the locking groove into the locking groove, while locking the rotating shaft 421 through the friction force, the rotating shaft 421 is locked by clamping, so as to improve the stability of the rotating shaft 421. Preferably, the locking groove is a cylindrical groove, and the end of the locking member 411 is a cylinder slightly smaller than the size of the cylindrical groove.

[0043] As Figure 6 shown in the figure, further, the fixture includes: a fixing frame 2, the fixing frame 2 is U-shaped, and a clamping space is formed by enclosing the inner side of the fixing frame 2; a threaded through hole, the threaded through hole is arranged on the fixing frame 2; a fixing part 9, the fixing part 9 is screwed into the threaded through hole, and the axial length of the fixing part 9 is greater than the axial length of the threaded through hole. During the process of connecting the frame body to the device to be installed, make part of the device to be installed enter the clamping space, and by rotating the fixing part 9, the fixing part 9 continuously extends into the inside of the clamping space and contacts the device to be installed, so as to realize connecting the frame body to the device to be installed. During the above connection process, the operation is simple, and there is no need for the device to be installed to have a matching installation part. As long as the part of the device to be installed that can extend into the clamping space can be used to install the fixture, the flexibility of fixture installation is enhanced. During the use process, the installation position of the fixture can be adjusted to adjust the position of the pushing member 3, so that the pushing head 6 at its end can push against the preset part of the patient during the movement.

[0044] Further, a rotating wheel 91 is arranged at one end of the fixing part 9 away from the fixing frame 2, and a handle 92 is arranged on the rotating wheel 91. The rotating wheel 91 is used to increase the torque, so that it is more labor-saving for the doctor to rotate the fixing part 9. The setting of the handle 92 is beneficial to increase a stable force application point, which is convenient for the doctor to apply a force to rotate the fixing part 9.

[0045] Further, it further includes a connecting member 5, and the clamp and the frame body are connected through the connecting member 5. The connecting member 5 plays a connecting role, mainly connecting the clamp and the frame body. Here, no specific limitation is imposed on the structure of the connecting member 5, as long as the effect of fixed connection can be achieved.

The ejecting member 3 is driven by the first rotary power source 7, making the ejector more automated. The physician does not need to operate and can control the movement of the ejecting member 3 by issuing corresponding instructions, reducing the workload of the physician, and the movement of the ejecting member 3 driven by the first rotary power source 7 is more stable and accurate. The first rotary power source 7 is preferably a manipulator, and the end of the manipulator is provided with an output end for outputting a rotary motion.

[0049] Further, the first rotary power source 7 is provided with an encoder, and the encoder is electrically connected to the first rotary power source 7. The encoder is used to record the rotation angle of the output end of the first rotary power source 7, and by recording the rotation angle, the rotation angle of the ejecting member 3 is recorded, thereby recording the moving distance of the ejecting member 3.

[0050] As Figure 3 、 Figure 4 shown, further, the frame body further includes a second rotary power source 8, and the second rotary power source 8 is connected to the rotating shaft 421. The second rotary power source 8 is connected to the rotating shaft 421, and the rotating shaft 421 is driven to rotate by the second rotary power source 8 to adjust the angle of the ejecting member 3, so that the ejecting member 3 can drive the ejecting head 6 to contact the preset part of the patient after moving. The second rotary power source 8 is preferably any one of a motor and a motor.
