Description

Technical Field

[0001] The invention relates to the field of object retrievers, and in particular to a medical object retriever. Background Art

[0002] In some surgeries, it is necessary to remove tissue samples for analysis or culture observation. During the operation, it is often necessary to complete the clamping action in a small space. In order to facilitate the operator to take samples, surgical or medical samplers are often used. These samplers are often narrow and long, so that they can be used in surgery after being sterilized.

[0003] In order to meet the needs of surgical operations, various medical sample extractors have appeared on the market. However, most of the existing medical sample extractors do not have a structure for opening the sample bag. As a result, the surgeon needs to hold the sample extractor with one hand and open the sample bag with one hand to put the sample into the bag, which is very inconvenient. Especially when the sample bag is too small or the operator wears surgical gloves, the operation is even more difficult. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention proposes a medical retriever to solve the technical problem of the difficulty in bagging of the prior art retriever.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A medical object extractor, comprising:

[0007] outer tube body;

[0008] The central shaft is sleeved in the outer tube body and slidably connected with the outer tube body, and one end of the central shaft protrudes out of the outer tube body; the other end of the central shaft is provided with a clamp for clamping the specimen;

[0009] The clamp comprises two clips, the two clips are arranged on the moving path of the central axis, a return spring is arranged between the two clips, so that the clips are tightly buckled together; the two clips are hinged to each other through a hinge, and the hinge is fixedly connected to the outer tube body; when the central axis moves toward the clips, the clips are spread open;

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] like Figure 1 and Figure 2 As shown, a medical specimen extractor comprises: an outer tube body 1, which has a through pipeline inside; a central axis 2, which is sleeved in the outer tube body 1 and slidably connected with the outer tube body 1, and one end of which protrudes out of the outer tube body 1; a clamp 9 is provided at the other end of the central axis 2 for clamping specimens; the clamp 9 comprises two clamping pieces, the two clamping pieces are arranged on the moving path of the central axis 2, and a return spring is provided between the two clamping pieces to make the clamping pieces tightly buckled together; the two clamping pieces are hinged The chains 12 are hinged to each other, and the hinges 12 are fixedly connected to the outer tube body 1; when the central axis 2 moves toward the clamp, the clamp is opened; at least two support claws 8 are arranged around the axis of the central axis 2, and are both hinged to one end of the outer tube body 1; two operating rods 3 are symmetrically arranged about the axis of the central axis 2, and are respectively hinged to the other end of the outer tube body 1; the transmission mechanism is constructed so that when the operating rod 3 rotates, the support claws 8 are driven to open, so as to open the storage bag, the retrieval bag or the specimen bag.

[0030] The working principle of the present invention is described in detail below. In this embodiment, in the initial state, due to the action of the reset spring, the clamp is in a tightened state. When the operator needs to clamp the specimen, he can first hold the fixed outer tube body 1 and push the central axis 2 so that the central axis 2 continues to squeeze the clamp. Under the squeezing action of the central axis 2, the angles of the two clamps increase until the clamp 9 is stretched open. When the clamp 9 is brought close to the specimen, at this time, stop applying thrust to the central axis 2. Under the action of the reset spring, the two clamps are buckled to clamp the specimen. After clamping the specimen, move the specimen to the mouth of the specimen bag, and then pinch the operating rods 3 on both sides to reduce the angle of the operating rod 3, open the support claws 8, and thus stretch the bag mouth to put the specimen into the bag.

[0031] It is understandable that in actual operation, the user can control the opening and tightening of the clamping piece by pushing the central axis 2 to complete the specimen clamping. When the specimen is against the mouth of the specimen bag, the supporting claw 8 is driven by rotating the operating rod 3 to open the specimen bag, and the specimen bag does not need to be opened manually, which is more convenient for specimen bagging.

[0032] Furthermore, the transmission mechanism includes two first connecting rods 4, two second connecting rods 7 and two third connecting rods 9. The first connecting rod 4, the second connecting rod 7 and the third connecting rod 9 are hinged in sequence. The two ends of the first connecting rod 4 are hinged to the second connecting rod 7 and the operating rod 3 respectively; the two ends of the second connecting rod 7 are hinged to the first connecting rod 4 and the third connecting rod 9 respectively, and the second connecting rod 7 is arranged along the axial direction of the outer tube body 1, and the outer wall of the outer tube body 1 is slidingly connected; the two ends of the third connecting rod 9 are hinged to the second connecting rod 7 and the supporting claw 8 respectively.

[0033] In this way, when performing actual operations, medical personnel can hold the sample extractor of the present invention with one hand. Specifically, medical personnel can use the middle finger and index finger to clamp the outer tube body 1, and make the end of the central axis 2 rest against the palm, so as to hold the entire medical sample extractor. Then, move the sample extractor to the specimen, and use the middle finger and index finger to pull the outer tube body 1 toward the palm, so that the central axis 2 pushes open the two clamps, and the two clamps open and approach the specimen, so that the specimen is located between the two clamps. At this time, move the outer tube body 1 away from the palm, and the clamps are reset to clamp the specimen. Then move the specimen to the specimen bag, and use the thumb and little finger to hook and press the operating rods 3 on both sides of the outer tube body 1 respectively. The operating rod 3 drives the first connecting rod 4, the second connecting rod 7 and the third connecting rod 9 in turn. Finally, the third connecting rod 9 rotates while the second connecting rod 7 slides, and the supporting claws 8 are opened, thereby opening the specimen bag. This setting facilitates one-handed control of picking up and bagging, making the operation more convenient.

[0034] More specifically, the end of the outer tube body 1 away from the clamp 9 is fixedly connected to a pull rod. When pulling the outer tube body 1, the medical staff can hold the outer tube body 1 with the index finger and the middle finger while hooking the pull rod to pull the outer tube body 1, which is easier and more labor-saving to operate. The end of the central axis 2 away from the clamp 9 is fixedly installed with a handle 11, which is arranged in an arc shape and is more comfortable when resting against the palm.

[0035] Furthermore, an elastic connector is provided between the operating rod 3 and the outer peripheral surface of the outer tube body 1, and the two ends of the elastic connector are respectively hinged to the operating rod 3 and the outer tube body 1. The elastic connector enables the operating rod 3 to be quickly reset.

[0036] In addition, an operating finger ring 10 is provided on the operating rod 3. When in use, the operating finger ring 10 can be hooked by the thumb and the little finger, making the operation more convenient. The operating rod 3 is constructed in an arc shape. An illuminating lamp is installed on the outer wall of the outer tube body 1 to provide illumination when the light is insufficient.
