BACKGROUND OF THE INVENTION Many different forms of delivery systems are known in the art to deliver effective medicaments for the prevention, treatment and treatment of diseases. „A delivery system is a subcutaneous injection implant that contains an effective agent < supply is and inserts an effective supply of time-consuming implants under the skin of an animal. Some different types of subcutaneous implants include permeation drug delivery Implants are degradable or erodible with pills or implants and expansion implants. Certain osmotic implant delivery systems are described in U.S. Patents 4,1 1.1,202; 4,11 1,203 and 4,203,439 . The process of placing a subcutaneous injection of osmotic infiltrate and placing an implant under the skin often uses a two-piece system trocar system, including a cannula and a pusher. When using this system, first look through the patient's skin One of the incisions, and the sleeve and the pusher through the skin, then pull out the pusher to make the sleeve a conductor of the injection implant. Insert the implant through the hole of the sleeve while pushing with the pusher to The end of the sleeve. The implant is then held in the appropriate axial position with the pusher, while the cannula is removed from the patient so that the implant is at a known position in the sleeve where the sleeve was previously placed. Then the sleeve and the pusher are placed Completely removed, leaving the implant In the position under the skin. This implant injection method includes removing the propeller for insertion into the implant and returning the propeller to the sleeve originally occupied by the propeller, and the position of the implant will be contaminated during the addition of these processes. However, it is difficult to insert the implant in the cannula at the insertion position before the cannula is inserted into the patient, because the implant is being inserted ~ 4-Benucius 7®® Home Sample Standard < CNsTA4 * i # · (210X297 / a ^) I--Γ ---- install-: ----- order ------ grade (please read the precautions on the back before filling this page) Ministry of Economic Affairs 夬Sample coordinator and shellfish consumer cooperation.

Specifically, when viewed in a cross-sectional direction, the end of the casing is cut by the first plane 48 and the second plane 50 as shown in FIG. 6. The first plane 48 forms an angle Si 'with the longitudinal axis of the sleeve and the second plane 50 forms an angle 02 with the longitudinal axis. The angle & is about 10 to 60 degrees, preferably 20 to 40 degrees, and the angle Θ 2 is about 5 to 45 degrees, preferably 5 to 25 degrees. The difference between the angular center and the center is between about 2 and 50 degrees, preferably between 6 and 35 degrees. The transition zone 52 at the end of the casing between the first plane 48 and the second plane 50 should preferably be a gradual or harmonic transition zone rather than a sudden transition zone. The gradual transition according to the present invention may be a slight figure just at the intersection between the first and second planes. Another way ' gradual transition may include extending about one-third of the curved surface along the end opening. This transition zone 52 is located in or between the top third of the casing and the top of the casing. The transition zone provides a slightly protruding protrusion in the insertion cannula that helps divide the muscle. The two different angles of the cannula tip according to the present invention provide reduced muscle fissures and tears when the trocar is inserted. Specifically, the shallower angle of the trailing edge 44 of the cannula 40 avoids damaging the interior or tearing the muscle when the cannula is inserted, and also avoids damaging the inner ring when the cannula is used to pierce its own foil package or implant package. As shown in FIG. 7, the rear edge 44 of the back end of the cannula should be fully retracted to protect the muscles from being caught on this rear edge when the implant is inserted. Reducing the edges 4 4 also prevents a complete muscular tissue from being cut by the cannula and damaging the interior. Reduce the trailing edge 4 4 and mix around the perimeter of the casing so that the mixing section is completely mixed into one of the mixing ends 5 4 located in the center third line of the casing.

Description of the Invention (9) Figures 8, 9 and 11 show the cannula used for the trocar according to the present invention An alternative to 60. The end of the cannula 60 has a cannula inserted into the muscle-the angled end, which includes the leading edge 62 and the trailing edge 64 of the cannula. As mentioned earlier, the end section includes a near rear edge The angle of 62 is smaller than the leading edge 64. This change in the angle of the end of the cannula helps to avoid tearing the muscle when the trocar is inserted. The cannula end 60 is provided with a leading edge 62 'with about half of the circumference of the cannula The reverse grinding section 6 6 = the reverse grinding section 66 is formed by the grinding operation that produces the oblique outer surface of the casing. The oblique grinding section 66 enables the front cutting edge 68 of the casing from the outer diameter of the casing Move to the inner diameter of the casing. The angle between the longitudinal axis of the casing 60 and the surface of the reverse grinding portion 66 is about 5 to 60 degrees, preferably 20 to 45 degrees. Although the inverse grinding portion 66 is shown to have a flat cross section, the grinding portion may also have a slightly convex or concave cross section. One of the advantages of the inverse grinding portion is compared with FIG. 1 〇 It can be seen from Figure 11. In Figure ^ 'the sleeve 80 according to the prior art is shown with an implant 82 shown in dashed lines. If the implant 82 slightly protrudes from the sleeve 80 during the insertion process, It is clear that one of the gaps 8 4 in which the tissue can be stored. This gap 8 4 of the prior art increases the muscle rupture and tear caused by the muscle sinking during the insertion. However, the inverse grinding part 6 shown in Figure 丨 丨 6 6 'The front cutting edge of the cannula with an inverse grinding section forces the muscles out of the implant 8 2 and does not squeeze into the space between the implant and the cannula to prevent muscle penetration and possible damage to the implant. Another advantage of section 66 is the improved cannula insertion situation caused by the angled surface pushing the muscles apart during the insertion process. The angled or beveled surface of the back-grinded section reduces muscle rupture and tear.

Description of the invention (10) Shao Fen 6 6 Improve the casing before advancement. For example, as shown in Figure] 0 angled scraping end (a traditional casing will be due to the angled end with the casing The axis of the tube is at an angle. However, the reverse grinding part 66 of the present invention provides a post-force during the insertion process to assist the casing to advance along a substantially axial path. Figures 丨 丨 also show The K-edge of the implant 82a located at a better position within the insertion cannula 60. The implant 82a can be held in this position by a pusher or another fixing device during the insertion process. When the front end of the implant 82a is located between the front edge 68 and the rear edge 64 of the cannula shown in Fig. ，, the edge of the implant will assist the side to divide the lobe into small fissures to tear the muscle and prevent damage to the interior. According to a better implantation method, the implant 8 2 a is located in the cannula between the front cutting edge 68 and the rear edge 64 and the third and the two thirds. The sleeves 20, 40, 60 according to the present invention may be made from any known sleeve material, such as plastic or metal. The indwelling trocar can be used once or multiple times. The trocar and trocar according to the present invention are used to insert implants in animals', including humans, domestic animals and the like. The invention has been described in detail with reference to preferred specific examples, but those skilled in the art will appreciate that various changes and modifications and equivalents can be made without departing from the principles and scope of the invention. n 1 L n.! u II— n I ·· 1 II 1 I __ τ I -III—-11.
