The utility model provides a PU (Poly Urethane) foaming wheel puncture experiment device, which relates to the field of PU foaming wheel performance and comprises a supporting mechanism, and a guide rail mechanism is fixedly connected to the top end surface of the supporting mechanism. According to the existing puncture test device, when a puncture tool is manually held by hand for puncturing, the efficiency is low, the puncture part of a foaming wheel is easily torn due to the fact that the puncture tool needs to be manually pulled out after puncturing is completed, and the test result is influenced. The vertical movement of the puncture assembly is controlled by the servo push rod, automation of the puncture process is achieved, compared with a traditional mode of manually holding a puncture tool, the structure improves the puncture efficiency, damage to the foaming wheel caused by manual pulling and inserting is avoided through the automatic reset function of the servo push rod, and the reliability of an experimental result is ensured.

This invention provides an upper limb positioning device for interventional cardiology procedures, belonging to the field of medical device technology. It includes a forearm support plate, a wrist support plate fixedly connected to one side of the forearm support plate, and a back-of-hand support plate fixedly connected to the side of the wrist support plate away from the forearm support plate. The forearm support plate, wrist support plate, and back-of-hand support plate together constitute a support and positioning mechanism for supporting and limiting the patient's upper limb. By setting up this support and positioning mechanism, this invention can provide wrap-around support and positioning for the patient's upper limb, effectively improving the fit and overall stability between the patient's upper limb and the support and positioning mechanism. This avoids unconscious rotation or lifting of the patient's upper limb during the procedure, eliminating problems such as needle displacement and vascular tearing, and effectively improving the overall safety of interventional cardiology procedures.

The utility model discloses a puncture needle, relates to the technical field of embryo transplantation, and aims to solve the problem that embryo transplantation cannot be realized when the genital tract of a patient is abnormal by a transplantation tube in the related technology. The puncture needle is used for embryo transplantation and comprises a needle tube, and the needle tube is a rigid tube; the first end face of one end of the needle tube in the length direction is obliquely arranged relative to the axis of the needle tube to form a needle tip, and the needle tip is used for entering a life body; a first included angle between the first end face and the axis of the needle tube is 15-20 degrees.

The application relates to a clamping jaw device, which comprises a first driving structure; the first transmission structure comprises a first transmission gear assembly and a first transmission shaft; a lifting piece is sleeved on the first transmission shaft and can move along the axial direction of the first transmission shaft under the rotation action of the first transmission shaft; a guide assembly comprises a first guide piece and a second guide piece; the first guide piece is connected to the lifting piece and synchronously lifts with the lifting piece; under the lifting action of the first guide piece, at least two second guide pieces are gathered or dispersed along the radial direction of the first transmission shaft; the at least two second guide pieces are gathered or dispersed so that a clamping piece clamps or releases an internal fixation needle. The clamping jaw device provided by the application can replace the manual grabbing of the internal fixation needle by a doctor, thereby relieving the hand fatigue of the doctor; through the feedback of the electric driving structure, the clamping force of the clamping piece on the internal fixation needle and whether the internal fixation needle has the clamping deviation phenomenon can be judged, thereby improving the puncture effect and puncture efficiency.

The present application relates to jujube processing technology field, specifically to a kind of jujube processing device, fixed with slide bar piece in mounting bracket, bearing frame is slidably installed on the slide bar piece;The present application also proposes a kind of jujube processing method, comprising the following steps: after jujube body is placed into bearing frame, jujube body falls in the upper end side of horizontal plate piece.This application can realize automatic operation, it is convenient to adjust according to the actual specification of jujube body, while effectively making reverse shaft and driving shaft piece reverse operation, can fully make jujube body can realize flat conveying, avoid the situation of accumulation conveying due to jujube material more, it can also effectively clamp jujube body and ensure its smooth movement, by the cooperation of corresponding components, jujube is cut and jujube kernel is pressed out, it is convenient to place walnut kernel into jujube in subsequent operation.

The utility model provides a kind of double-arm puncture positioning mechanism and puncture robot, wherein double-arm puncture positioning mechanism includes: two parallel interval settings linear motion unit, two movement swing arms, probe angle adjusting unit, probe, puncture angle adjusting unit and puncture execution unit;Wherein, linear motion unit is used to adjust the position of movement swing arm in first direction;One movement swing arm is used to adjust the position of probe angle adjusting unit in second direction and third direction;Another movement swing arm is used to adjust the position of puncture angle adjusting unit in second direction and third direction;Probe angle adjusting unit is connected with probe and is used to adjust the deflection angle of probe;Puncture angle adjusting unit is used to adjust the pitch angle and deflection angle of puncture execution unit.By adopting the above technical scheme, the adjustment accuracy and flexibility of the puncture robot are improved.
