The invention has the advantages that the actions of cutting and stitching can be completed at a time, the speed of operation is increased, and the pain of patients can be alleviated.

The invention discloses a minimally-invasive interventional operation robot for the urinary surgery. A flexible ureteroscope lifting module comprises a lifting table and a linear module fixing rack, the lifting table can adjust the height of a flexible ureteroscope and a sickbed, and the fixing rack is connected with the lifting table and a linear module; a flexible ureteroscope pushing module comprises a pushing mechanism and a flexible ureteroscope supporting mechanism, and can be used for pushing the flexile ureteroscope, and the supporting mechanism is used for providing a flexible part supporting force for the flexible ureteroscope; a flexible ureteroscope rotating module comprises a rotating shaft and a gear and drives the rotating shaft to rotate through rotation of a motor; a flexible ureteroscope bending module comprises flexible ureteroscope fixing support, a flexible ureteroscope carrying platform and a U-type knob which is matched with a flexible ureteroscope bending knob,and the flexible ureteroscope bending knob rotates along with rotation of the U-type knob. The minimally-invasive interventional operation robot can help a doctor to operate the flexible ureteroscopecorrespondingly during the surgery, relieve fatigue caused by the long-time surgery of the doctor, increase the speed of the surgery, and collect force data of flexible ureteroscope motion during thesurgery.

The arm fixing device comprises a bottom plate, an arc-shaped supporting plate is fixedly connected to the upper side of the bottom plate, the two ends of the upper side of the bottom plate are each fixedly connected with a vertical plate, the upper sides of the two vertical plates jointly support and are fixedly connected with an arc-shaped plate, the arc-shaped plate is slidably connected with a downward pressing device, and the downward pressing device comprises a guide block; the arc-shaped plate is provided with a guide hole, the guide block is slidably connected in the guide hole, the guide block is provided with a through groove, and a plurality of pressing units are slidably connected in the through groove; the pressing unit comprises a guide rod, a pressing block is arranged at the lower end of the guide rod, and an arc-shaped groove is formed in the bottom of the pressing block. By rotating the synchronous wheel, the first pressing block is lifted up to reduce the conveying resistance, and the subsequent pressing block is lifted up along with further penetration of conveyed equipment to reduce the conveying resistance, so that when the arm is clamped, the influence on equipment conveying is reduced to the maximum extent, and the operation speed is increased.

The invention relates to a pair of oral forceps, comprising a fixed axis, forceps arms and a forceps jaw, wherein the front end of the forceps jaw is tilted to form a forceps nose; a reflector is fixedly installed on the fixed axis and is parallel to the forceps jaw; the light-reflecting surface of the reflector is opposite to the forceps jaw which is capable of freely moving relative to the reflector; through holes are perforated in equidistant arrays in the mirror surface of the reflector; an air suction cavity is fixedly installed on the back side of the reflector; the through holes are communicated with the air suction cavity; a saliva storing tube is sleeved with the forceps arms and communicated with the air suction cavity through a catheter; an air suction ball is also installed on the forceps arms; and the air suction end of the air suction ball is connected with the saliva storing tube. The oral forceps have the advantages of exquisite structure and convenient operation, have multiple functions such as pressing a tongue and sucking saliva, effectively reduce the difficulty in operation technique and improve the operation efficiency.

The invention provides a cheekbone positioning fixing apparatus, which comprises two forceps bodies consisting of forceps handles and forceps heads. The two forceps bodies are connected in a crossed manner via a hinge pin, a finger ring hole and a fixing clamping tooth are arranged at the rear end of each forceps handle, the fixing clamping teeth on the two forceps handles match mutually, claw hooks are arranged at the front ends of the two forceps heads, the plane with the claw hooks is perpendicular to a plane with the forceps handles, a plane with mouths of the claw hooks is parallel to the plane with the forceps handles, a conical groove is arranged on the inner side surface of each claw hook along the length direction of the claw hook, and the grooves on the inner side surfaces of the two claw hooks correspond to each other. The cheekbone positioning fixing apparatus is firm in clamping, cannot slip, guarantees surgery quality, shortens surgery time, can well realize that a bone stump of a cheekbone after a part of the cheekbone is cut off is fixed stably and reliable in the facial contouring industry, can utilize absorbent threads or nylon threads to replace steel wires for fixation or miniature titanium steel plate screws for fixation, and eliminates the drawback that metal foreign bodies are remained in the face of a patient forever.

The invention belongs to the technical field of medical appliances, and specifically discloses a minimally invasive laparoscopic retractor. The minimally invasive laparoscopic retractor comprises a sleeve ring, a conductor, a support tube and a movable tube; the conductor is composed of a plurality of conduction rods and a conduction ring; the support tube is composed of a plurality of support rods and a support ring; the lower end of each of the support rods is fixedly connected with a rubber block; a cavity is formed inside each of the rubber blocks; two arcuate elastic pieces are fixedly connected with the interior of each of the cavity; third grooves, which are in one-to-one correspondence with sliding rods, are formed on a surface of the movable tube; second guide grooves communicatethrough the third grooves; ejector cores are connected with the interior of the third grooves in a sliding way; and the ejector cores are fixedly connected to the inner walls of the second guide grooves by evenly distributed springs. The minimally invasive laparoscopic retractor is capable of avoiding influence on surgery by effectively preventing closure of an opening during operation, thereby reducing the probability of secondary injury to subcutaneous tissue caused by medical instruments during the operation; moreover, the minimally invasive laparoscopic retractor is also capable of allowing more quickly and conveniently cleaning of a patient's wound with physiological saline.
