FIGS. 1-6 are schematic views of a laparoscopic surgical instrument; fig. 7 is a schematic view of an enlarged top cover.

In some alternative embodiments, as shown in fig. 1-6, an instrument for laparoscopic surgery is provided, which comprises an instrument shaft 1, wherein a plurality of scale marks 11 are uniformly arranged on the instrument shaft 1. Here, the position of the graduation marks 11 is determined by pre-measurement, arranged recessed in the surface of the instrument shaft 1. Therefore, when in use, the instrument rod 1 is pressed against the polyp or other lesion tissues, and the size of the polyp or other lesion tissues can be accurately judged through the scale marks 11 on the instrument rod 1, so that a doctor can conveniently adopt corresponding treatment means.

In some alternative embodiments, as shown in fig. 1 and 3, the total length of the tube section of the instrument shaft 1 provided with the graduation marks 11 can be in the range of [10cm, 15cm ] (cm: cm). The overall length of the tube section of the instrument shaft 1 provided with the graduation marks 11 is adapted to the size of the pathological or other tissue in general, so that the application range of the instrument shaft 1 is expanded.

In some alternative embodiments, the distance between any two adjacent tick marks 11 is 1 cm. Here, the interval between adjacent scale marks 11 is set to be 1cm, so that the size of lesion tissues can be accurately measured, and meanwhile, the problem that the interval between the scale marks 11 is too small, so that a doctor difficultly checks the scale value and normal examination is influenced is avoided.

In some alternative embodiments, as shown in fig. 1-2, the instrument shaft 1 is provided with a ring-shaped graduation mark 111 at intervals of a set length, i.e. a graduation mark 11 arranged around the periphery of the instrument shaft 1. For example, the ring-shaped scale 111 is provided at the start position of the scale of the instrument bar 1, the 5 th scale 11 position (5 cm), the 10 th scale 11 position (10 cm), and the 15 th scale 11 position (15 cm). The ring-shaped scale lines 111 are relatively obvious, so that doctors can conveniently and accurately judge the size of the lesion.

In some alternative embodiments, as shown in fig. 1-2, the instrument shaft 1 has one concave marking slot 12 at every set length. For example, the mark groove 12 is provided at a position (2.5 cm) between the 3 rd and 4 th scale positions, a position (7.5 cm) between the 8 th and 9 th scale positions, and a position (12.5 cm) between the 13 th and 14 th scale positions of the instrument lever 1. Generally, the positions of the 3 rd and 4 th graduation lines 11 are easy to mix among the 6 graduation lines 11, and the marking groove 12 is arranged at the middle position of the graduation line, so that the position is highlighted and marked, a doctor can accurately judge the size of a lesion according to the position, and the diagnosis accuracy of the doctor is improved.

In some alternative embodiments, as shown in fig. 3-4, the marking slot 12 includes a first marking slot 121 and a second marking slot 122 with different shapes, and the first marking slot 121 and the second marking slot 122 are alternately arranged. For example, a first marking groove 121 is provided at a starting position of 5cm, 10cm and 15cm of the scale of the instrument bar 1, and a second marking groove 122 is provided at a position of 2.5cm, 7.5cm and 12.5cm of the instrument bar 1. Here, the first marking groove 121 may be a circular groove, and the second marking groove 122 may be a triangular groove. Like this, when the scale mark 11 of the edge butt of pathological change tissue be the first scale mark 11 of the triangle-shaped recess behind the second circular recess, can confirm that this pathological change tissue's size is 8cm, according to first mark groove 121 and the size of the supplementary pathological change tissue of confirming of second mark groove 122, faster, the accuracy is higher.

In some alternative embodiments, the bottom of the marking slot 12 is provided with a marking number 13 corresponding to the position of the marking slot 12, and the marking number 13 is a numerical value of the length represented by the marking position. In this way, the physician can be assisted in visually determining the size of the lesion tissue or other tissue to be measured on the basis of the reference numeral 13.

In some alternative embodiments, as shown in fig. 7, the laparoscopic surgical instrument further includes an enlarged cap 2, and the enlarged cap 2 includes a cap body 21 and an enlarged lens 22, wherein the cap body 21 is covered on the marking groove 12, and the enlarged lens 22 is embedded in the cap body 21 for enlarging the marked number 13. Optionally, the magnifying glass 22 is a convex lens. Thus, because the marked number 13 in the marking groove 12 is smaller, the marked number 13 is enlarged through the magnifying lens 22, so that a doctor can clearly see the marked number 13 more conveniently, and further determine the size of the object to be measured.

Optionally, the periphery of the top cover body 21 is provided with an external thread structure 211, the inside of the marking groove 12 is provided with an internal thread structure, and the enlarged top cover 2 is fixed in the marking groove 12 through the thread structure to prevent slipping from the marking groove 12.

In some alternative embodiments, as shown in fig. 5-6, the instrument stem 1 includes alternating first and second tube segments 14, 15, the first tube segment 14 having an outer diameter greater than the outer diameter of the second tube segment 15. For example, the tube sections located at 0-5cm and 10-15cm of the instrument bar 1 are first tube sections 14, and the tube sections located at 6-10cm and 15-20cm of the instrument bar 1 are second tube sections 15. When the scale mark 11 abutted against the edge of the lesion tissue is positioned on the second first pipe section 14, the size of the lesion tissue can be determined to be more than 10cm, so that a doctor can be assisted to determine the size of the tissue to be detected according to the outer diameter of the pipe section, and the accuracy of judgment is improved. Here, the outer diameter of the instrument bar 1 is changed alternately, the inner diameter of the instrument bar 1 does not change, and the structure of the optical structure inside the instrument bar 1 is not affected.

In some alternative embodiments, the instrument shaft 1 includes alternating third and fourth tube segments, the third tube segment having a different coating on its surface than the fourth tube segment. For example, the surface of the pipe sections at the positions of 0-5cm and 10-15cm of the instrument rod 1 is coated with a white coating, and the surface of the pipe sections at the positions of 6-10cm and 15-20cm of the instrument rod 1 is coated with a red coating. When the scale mark 11 abutted against the edge of the lesion tissue is positioned on the second third pipe section, the size of the lesion tissue can be determined to be more than 10cm, and thus, doctors can be assisted to determine the size of the tissue to be determined according to different coatings of the pipe sections, and the accuracy of judgment is improved.

It is to be understood that the present invention is not limited to the procedures and structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
