Problems solved by technology

The inventor found that most lightweight surgical robots use gear transmission, which is expensive to manufacture and complicated to maintain, and does not have good shock absorption
Moreover, most surgical robots do not complete the gravity balance of the surgical robot, but only rely on the motor rotor to lock the balance, which increases the load on the motor, and cannot guarantee the safety of the surgical robot. cause irreversible damage
[0004] Chinese patent document (publication number CN210354897U) discloses a minimally invasive surgical manipulator with a parallelogram structure, which uses a motor to directly drive the skeleton, which requires high motor load, weak impact resistance, and does not have gravity balance. maintain posture
On the whole, too much freedom in the series structure leads to insufficient rigidity and bearing capacity of the surgical actuator, and there is no rigid compensation mechanism, which makes it difficult to achieve the accuracy required for surgery

Embodiment 1

[0036] Such as Figure 1-5 As shown, a freely installable miniature bedside surgical robot disclosed in the present invention includes a base, an operating arm, and a quick-change mechanism.

[0037] There is a rotating frame on the base, and a rotating motor on the rotating frame, which is used to control the tilting and swinging of the rotating frame in the horizontal plane; a driving motor is installed in the rotating frame, and the driving motor is connected with the operating arm, and the driving motor is used to drive the operating arm. Movement in the vertical plane.

[0038] The surgical arm includes a forearm rod group and a rear arm rod group. It is a double-plane four-bar linkage mechanism composed of a forearm rod group and a rear arm rod group. The forearm rod group includes two parallel forearm rods 1 and two forearm rod 2 , the rear arm group includes two parallel rear arm rods 1 and 2, the forearm rod 1 and the forearm rod 2 are hinged through a connecting rod...

Embodiment 2

[0041] A miniature bedside surgical robot that can be installed freely, its structure is as described in Embodiment 1, the difference is that the output shaft of the rotating motor is connected with the active synchronous pulley, the active synchronous pulley meshes with the driven synchronous pulley, and the front end of the rotating base There is a support frame, the top of the support frame is installed with a rotating shaft fixing buckle, and the buckle has a built-in bearing. A swivel joint, one end of the swivel joint is placed in a snap-in built-in bearing. When the rotating motor rotates, the rotating frame is tilted through the two pulleys, and the rotating joint together with the rotating frame rotates in the bearing built in the buckle, so that the whole body tilts and swings in the horizontal plane to adjust the posture.

Embodiment 3

[0043] A kind of freely installable miniature bedside surgical robot, its structure is as described in embodiment 2, the difference is that the output shaft of the driving motor is connected with the small synchronous pulley, and the small synchronous pulley moves synchronously with the large synchronous pulley through the synchronous belt, The large synchronous pulley is in interference fit with the large synchronous pulley shaft, and the large synchronous pulley shaft is connected to the two rear arm bars through interference fit. The rotation of the back arm is driven by the rotation of the synchronous pulley, which in turn drives the overall movement of the operation arm.

Abstract

The invention relates to a freely installable miniaturized bedside surgical robot and its working method, comprising a base, an operating arm, and a quick-change mechanism; The rotating frame tilts and swings in the horizontal plane; there is a driving motor in the rotating frame, which is connected with the operating arm, and the driving motor is used to drive the operating arm to move in the vertical plane; the operating arm includes a forearm rod group and a rear arm rod group, which are A double-plane four-bar linkage mechanism composed of a front arm group and a rear arm group; one end of the forearm group is provided with a quick-change mechanism, and the quick-change mechanism includes a support platform, and an actuator mechanism and an actuator rod are arranged on the support platform. The control actuator is micro-operated at the end. The structure is lightweight, the principle is clear and the structure is simple, the number of installations can be freely selected according to requirements, and the cost is low, which can meet the requirements of general multi-hole laparoscopic surgery for machine devices.

Description

technical field [0001] The invention relates to a freely installable miniaturized bedside surgical robot and a working method thereof, belonging to the technical field of medical devices. Background technique [0002] Laparoscopic surgery, also known as minimally invasive surgery (MIS), is a surgical technique performed through multiple small 0.5 to 1.5 (cm) incisions in the abdominal wall. Compared with traditional laparotomy, this technique greatly reduces the size of the incision for the patient, so it has many advantages, such as smaller postoperative scars, less postoperative pain, and shorter hospital stay. Because of these clinical benefits, various attempts have been made to minimize invasiveness, resulting in single-incision laparoscopic surgery (SILS). Because only one incision is required at the umbilicus, the clinical benefit is significantly improved. However, most current single-incision laparoscopic surgical platforms either lack traction, or are not suffici...
