Embodiment 1

[0042] Combined with the manual Figure 1-Figure 4 The precise spatial positioning puncture device shown is composed of a positioning puncture mechanism with four-axis compound motion and an installation mechanism for installing the positioning puncture mechanism. The positioning puncture mechanism consists of an arc arm 2, a pitch mechanism 3, a deflection Mechanism 4 and mobile mechanism 5 are composed;

[0043] Both ends of the arc arm 2 are hinged on the installation mechanism 1, the pitch mechanism 3 is driven to connect the arc arm 2 and the installation mechanism 1, and the deflection mechanism 4 is slidably arranged on the arc arm 2 , the moving mechanism 5 is slidably arranged on the lower part of the deflection mechanism 4, a reciprocating needle holder 54 is installed on the moving mechanism 5, and the needle holder 54 has at least one needle holder. The arc arm 2 is arranged in a semicircle, and the axis where the hinge point of the arc arm 2 and the mounting seat...

Embodiment 2

[0047] This embodiment is a further detailed design for the pitch mechanism 3 in terms of the structure and principle of the embodiment 1, and it is also one of the two technologies of the application. Specifically, the pitch mechanism 3 includes fixed installation on the installation The second rack 31 on the mechanism 1 and the second servo motor 32 installed on the arc arm 2, the second servo motor 32 is drivingly connected to the second rack 31 through a second drive gear 33; The plane where the second rack 31 is installed is perpendicular to the plane where the arc arm 2 is located. The key point of the puncture device is the accuracy of puncture. When pitch adjustment is required, if a conventional hinged shaft is used for driving, it will have an error amplification effect on the needle holder 54, that is, because the needle holder 54 is the final installation of the puncture needle. structure, its spatial position is affected by the size and sliding position of the mov...

Embodiment 3

[0053] On the basis of embodiment 2, further in conjunction with specification sheet Figure 5-Figure 9 As shown, this embodiment also refines the structure of the deflection mechanism 4 and the moving mechanism 5 respectively. Specifically, the second sliding rail 21 and the arc rack are fixedly installed on the arc arm 2, and the deflection The mechanism 4 is slidably installed on the second slide rail 21, the deflection mechanism 4 includes a first bracket 41, a third servo motor 43 installed on the first bracket 41, and is used to clamp the second slide rail 21. A roller 42 and a third slide rail 48 for installing the moving mechanism 5, the positions at both ends of the third slide rail 48 above the first support 41 are respectively provided with fourth slide rails connected by the first anti-skid belt 45. Servo motor 44 and first driven wheel 46'. The deflection mechanism 4 also includes a first card holder 47 fixedly connected to the first anti-skid belt 45 and slidabl...

Abstract

The present application discloses a precise spatial positioning puncture device, which consists of a positioning puncture mechanism with four-axis compound motion and an installation mechanism for installing the positioning puncture mechanism. The positioning puncture mechanism consists of an arc arm, a pitch mechanism, and a deflection mechanism. It is composed of a moving mechanism; the two ends of the arc arm are hinged on the installation mechanism, the pitch mechanism drives and connects the arc arm and the installation mechanism, and the deflection mechanism is slidably arranged on the arc arm. The moving mechanism is slidably arranged on the lower part of the deflection mechanism, and a reciprocating needle holder is installed on the moving mechanism. The present invention realizes no-blind puncture by adopting four-axis linkage, and can perform precise puncture on complex and blocked target parts; at the same time, the present invention can realize pitch positioning with almost negligible error by adding a pitch mechanism creatively, overcoming the Due to the large size of the arc arm, the error is magnified, resulting in the problem of reduced positioning accuracy.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a device for surgical puncture, in particular to a precise space positioning puncture device. Background technique [0002] Needle biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of examination methods and methods, the correct rate of diagnosis has gradually increased, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. A correct diagnosis requires a combination of clinical, imaging, and pathological factors. Among them, pathological diagnosis pl...
